So I’ve been with my current boyfriend for 9 months now and we’ve been intimate for 6 months. Everything was fine up until around 4 months ago. I haven’t gotten my period in around 55 days. My periods were always regular, on time and very predictable but now i have no idea whats going on. I have taken 8 pregnancy tests over the past few months which have all come up negative. Ever since my period stopped sex with my boyfriend has become somewhat sore and i have bled 3 times afterwards. I get sharp cramps in the left side of my lower stomach often and this has been occurring both when i was on my period and when I wasn’t (Pain has been very frequent since my period stopped)

PLEASE HELP! Im very worried. Could i be pregnant? Or does any one have any idea whats wrong with me?
