My last period was 12/26, and I have had unprotected sex more than 4 times since. About 6 days after one instance, I had very light pink spotting when I wiped after using the bathroom, and it lasted about 2 hours. I have been having slight cramping, I feel bloated, and my nipples are larger than usual. Also, I have been having heartburn more than usual, and on a few occasions, it feels like I am going to vomit. One more thing, I am not sure if it is related or not, but I have been feeling a lot more horny lately.
It is too early to take a pregnancy test, but I feel like I might be pregnant. I was just hoping somebody could offer me some feedback on the situation. Could I be pregnant?
