I stopped the depo on the 12th of February. I had sex on the 21st of February and about 4 or 5 days ago my nipples got sore and still are. I’ve been nauseous and throwing up but the pregnancy test showed up negative. I went to the doctor and they said the same thing. This is a little tmi but do you think this is just spotting or could it be implantation bleeding? Please help. I really want a baby and I’ve been trying for what seems like forever... lol
