AF 12 days late. Could I be pregnant!?

I was suppose to get my period on the 3rd of November. I’ve been having cramps on both sides of my stomach, pain in my breast, nausea, bloated, and tiredness.

I did have unprotected sex on the 13th. My fertile days were 14-19 (I believe) and I’ve been having those symptoms for about 2 weeks now. I did take a pregnancy test on the 29th of October and the 11th of November they were both negative. My bf and I really do want children it’s just been hard. Hopefully it’s our time. Baby Dust 👶🏽
