Hello I've been having pregnancy symptoms . my boobs hurt to touch and feel very sore. My nipples are erect. Boobs look bigger feel bigger too. I've had negative tests. I stopped my pill on the 4th its now the 23rd
I haven't had a period for over a year due to my pill. I'm very confused. I've been having unprotected sex since stopped the pill on the 4th
