Hi, I had protected sex on April 10th, one day after my period ended. I have a period tracker on my phone and I was supposed to start yesterday, May 3rd. My periods are usually regular, however sometimes they have switched around from starting at the beginning of the month and starting at the end of the month. When he pulled out, after ejaculating inside the condom, he didn't seem to notice anything amiss and I watched him pull out. He was holding the opening of the condom so it didn't slide off. I'm 95% sure it didn't break. This was my 3rd time having sex, and the other 2 times were protected. One happened last March and the other last August, and I had periods like normal after those two times. I know being a day late isn't much cause to freak out, but my breasts have been sore, which just started a few days ago. However, I always have that symptom before my period starts, but I've been reading that it's also a symptom of pregnancy. Other than that, I've been having no other symptoms. I'm 20 yrs. old and really scared!
