Long story but here goes: The date of my last real period was October 28th, 2016. I had unprotected sex November 4,5,6, and 7th. I know for a fact that my boyfriend wasn't as careful as he usually is (if you get what I'm saying). I was due for my period on November 27th but it was super light and only for 2/3 days. My period never came in December. I had/have mild cramping which I usually get prior to my period starring, I feel achey, I have been nauseous and my nipples have been very sore for almost a week. Today my nipples are no longer sore but I took an at-home test late last night (around 10:30PM) and it was negative. My period still hasn't came and I have never been late before. Any advice would be greatly appreciated.
