Hi I'm 19 and have been on yaz bc for 2 ish years because of an iron deficiency. 2 months ago I had unprotected sex but since then I have had 2 periods(lighter than usual I think) and my next should start in a few days. I don't have many pregnancy signs but sometimes I feels as if I could be and the last day or two my breasts have been sore and the nipples look enlarged. I wanna know if there is a probability that I am pregnant.
