Hey girlie- I found a little bit of information for you!

when should I avoid sex?
Assuming your pregnancy is normal and low-risk, you shouldn't have to say no to a roll in the hay. In fact, many couples continue their sex life right up to their baby's delivery. Neither intercourse nor orgasm poses a threat to a healthy pregnant woman or her baby. The thick mucus plug that seals the cervix during pregnancy helps guard against infection. And the baby is well protected by the fluid-filled amniotic sac and strong uterine muscles.
However, if you're having a high-risk pregnancy or your practitioner anticipates any complications, you may have to forgo sex. (and of course, if you notice any unusual symptoms during or following intercourse, such as pain or discharge, call your doctor or midwife before having sex again.)
because orgasm can cause mild uterine contractions (as can the prostaglandins in semen), most doctors and midwives will advise against intercourse if you have any of the following conditions: an increased risk for miscarriage
placenta previa or a very low-lying placenta
a history of preterm birth
premature labor if you're less than 36 weeks pregnant
unexplained vaginal bleeding or discharge
abdominal cramping
an "incompetent cervix"
a dilated cervix
ruptured membranes (your water has broken)
an unhealed herpes lesion in either you or your partner, or the presence of any other sexually transmitted disease. In this case, abstain from sex until you and your mate have been treated and a follow-up test shows you're both free of disease. If your partner is hiv positive, and you have sex while you're pregnant especially without a condom you could be putting yourself and your baby at risk for contracting the disease.
If you have to forego sex, don't despair: you can still kiss, engage in creative foreplay, give each other long massages, and share your feelings for each other.

can I have sex while i'm pregnant?
Absolutely. With a normal pregnancy, you can keep doing it right up until your water breaks. Do check with your doctor or midwife first if you've been treated for premature labor or if you're having any problems with your pregnancy, such as a shortened or dilated cervix, leaking amniotic fluid, placenta previa, or bleeding, or if you have a history of miscarriages. There are some instances when you should avoid having sex.
But as long as your pregnancy is normal, you won't hurt the baby by making love, even with your partner on top. The thick mucus plug that seals the cervix helps guard against infection. The amniotic sac and the strong muscles of the uterus also protect your baby. Though your fetus may thrash around a bit after orgasm, it's because of your pounding heart, not because he knows what's happening or feels pain.
Will it feel as good?
Even better for some women, not as good for others. Increased blood flow to the pelvic area can cause engorgement of the genitals and heighten the sensation. But the same engorgement gives other women an uncomfortable feeling of fullness after intercourse ends. Also, some women may have abdominal cramps during or after intercourse. Your breasts may become enlarged and can be more tender, which can cause discomfort when they're fondled. You may have more vaginal discharge or moistness, which can make sex either more pleasurable or can result in some vaginal irritation. If you notice a sudden change in the amount of vaginal discharge or a foul or unusual odor, check with your practitioner. You could have a vaginal infection or your bag of waters may have broken. When your water breaks, you may feel a slow leak rather than a gush of fluid all at once.
I haven't really been in the mood since I got pregnant. Is this normal?
Yes, it can be. The big changes in your body are bound to change your sex life. Some women, finally free from worries about conception and contraception, feel sexier than ever. But others are just too tired or nauseated to make love, especially in the first trimester. The second trimester is often marked by a resurging libido. Your desire may wane again in the third trimester as birth, labor, and your belly loom large, or you may simply feel unattractive or tired.
Will my partner's sex drive change?
Most people find their pregnant partner as attractive as ever. But your partner's desire may be dampened by concerns for your health and the baby's, apprehension about the burdens of parenthood, fear that sex can hurt the baby, or even self-consciousness about making love in the presence of your unborn child.
Is oral sex safe?
Yes, oral sex won't harm you or your baby, provided you're in a monogamous relationship where both you and your partner are hiv-negative. In fact many consider it a nice substitute if intercourse is deemed too risky. If you're not sure what your partner's hiv status is, then you need to use a dental dam (a sheet of latex that you place between your genitals and your partner's mouth) because there's some evidence suggesting that a person may be able to transmit hiv through micro-abrasions or tiny cuts in his mouth.
Which positions are the most comfortable?
Here are some time-tested positions and tips for making love while you're pregnant:
lie sideways. Having your partner on top demands increasingly creative gymnastics as your tummy swells. But lying partly sideways allows your partner to keep most of his weight off your uterus.
use the bed as a prop. Your bulge isn't an obstacle if you lie on your back at the side or foot of the bed with your knees bent, and your bottom and feet perched at the edge of the mattress. Your partner can either kneel or stand in front of you.
lie side-by-side in the spoon position, which allows for only shallow penetration. Deep thrusts can become uncomfortable as the months pass.
get on top of your partner. It puts no weight on your abdomen and allows you to control the depth of penetration.
have your partner enter you from a sitting position, which also puts no weight on the uterus. Try sitting on your partner's lap as he sits on a sturdy chair.
Have faith where there's a will, there's a way. With a little experimenting, you and your partner are sure to find a technique that works for you.
Hope this helps,
