Hi so me and my fiancé had intercourse Saturday, Feb. 11 at about 2am. We did go out and have a few drinks. Tuesday morning at around 9am He decided to tell me that he didn't use protection ( I was unaware). I immediately rushed to CVS to buy Aftera, morning after pill. I took it and I went on my app where I record my menstrual cycle along with intercourse and it turns out that we had intercourse during my fertile window. Now I'm afraid that I could be pregnant because I took the pill 80hrs later. Now its 12dpo and I'm feeling very tired. my breasts are sore and I'm having light spotting/bleeding with mild cramping. My periods are usually always HEAVY and I get bad cramping. I don't know when to take a HPT. I need opinions.
