My boyfriend and I decided to not use a condom for literally 5 strokes in the beginning and then we just put on a condom and continued. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> is saying that my period is five days late. My periodhas always skipped around. It used to start around the 20s. Then it slowly worked its way backwards in the month. Now it normally starts around 10th or so. I don't think I've shown any pregnancy symptoms. It is driving me crazy not knowing if I am or not. My friend has had the same scare as me before and she turned out okay. I'm a very worrisome person, I worry about everything. So, you can only imagine how bad this is. My friends doctor told her that getting pregnant from pre cum is pretty slim and rare cases. So it is highly unlikely. Btw our condoms have not broken before either. We always double check and keep extras near by so we can make sure everything is okay. I know that studies have shown that precum doesn't have sperm. Usually dead sperm. But anyways, my boyfriend never came. Do I really need to be worried? I read that a change in work outs can delay periods and also more stress. I started working out and was sore for more than three days. I have also been stressing over my period not being here. Another thing, we had sex at the very end of my last period. So, I read that that is the time that you are least likely to become pregnant. please help and give opinions or past experiences?!
