symptoms of body ovulating

Okay, so I'm going to try to make this as[i] short [/i]as I can while still telling my story. My husband and I have a two and a half year old son and a 10 month old daughter. I'v been pregnant three times... I miscarried once beofre we concieved our son. None of our pregnancies were planned. We were using condoms the first time I got pregnant... we used the pull out method ONCE and that's how we got pregnant. The second time I got pregnant. I was on birthcontrol...and along came our son! The third time I got pregnant, we were using condoms about 80% of the time and the pull out method when we didnt' use condoms (guess we didn't learn from our mistakes. Anyways, I am not on any kind of birth control now (I know, I know...I need to be!) BUT, condoms have never failed us and we are using them now. Okay, now here is my concern: Sometimes, during foreplay, my husband will insert a few times without a condom. My last period ended around the 27th of January (it was a normal period btw). Well, the last few days, I'v felt a little sick to my stomach, I'v had a really thick white discharge, and my breats have been slightly sore. Now, I don't want to jump to conclusions, it's just that odviously I get pregnant easily and any sign of pregnancy totally freaks me out. So, my quesiton to you is... 1. Don't you ovulate about 2 weeks after your period? 2. Could these symptoms simply come from my body ovulating? Kinda confused and little worried! Any answers would be a great help!!! :shock:

Thanks so much,
