Hello,
I've been through all that. My husband and I tried for 4 years and I am now 3 months pregnant.
We finally got to the Fertility Clinic and they found the problem!
What I did - might help you:
-CLOMID tablets to make sure you ovulate
-Vaginal Ultrasound to detect a pregnancy immediately - Dr should be able to see the yolk sac by 4 weeks-6weeks.
-400 mg daily of PROMETRIUM (Progesterone) to fluff up your uterus lining so that the embryo can implant.
-Now, you could start taking daily: just 1 tablet of Child Aspirine & 1 Prenatal Vitamin.
-If you are underweight, increase your carbohydrate intake (Pastas, Bread, there's a good high fiber Pasta called Catelli Smart Pasta).
-I also went for acupuncture to fix my cycle! If you have an absence of your period, an Acupuncturist can start that back up!
-When you do ovulate, make love on the right days (usually days 9-19 of your cycle) and only once per day to keep the sperm more potent, and stay laying down to prevent the sperm from slipping out. ALSO, have an orgasm after love-making so that your cervix & uterus dip down into the pool of sperm laying in your vagina.
GOOD LUCK!!
