Hello :) my period hasn’t come since April and I lost my virginity April 29th and then did things again a couple times after (not protected) and I haven’t had my period since. I’ve taken at least 4 pregnancy test and al negative but my boobs have been super tender, I’ve got this faint lime on my stomach that wasn’t there before, I’m always tired and nauseous and I haven’t really been eating much unless it’s something I’m really craving. Can anyone explain to me what might be going on if I got negatives ?
