I'm 19 years old and about a week and a half ago I got what I thought was my period, (my periods have always been all over the place and quite irregular). It started with a brownish discharge for a couple of days and then i began bleeding, but it was slightly lighter than my period would usually be, also i didn't experience much discomfort (cramps) which isn't usual for me. The bleeding lasted about 6 days then stopped yesterday and i had sex with my boyfriend last night, three hours later i had severe abdominal cramps and felt light headed and weak i started bleeding very heavily and a large blood clot fell onto the bathroom floor as soon as i undressed. I have continued to bleed ever since but it has calmed down a lot. (I should also point out that I only lost my virginity in the last couple of months, im not sure if this is relevant or not.) As far as i am aware i was and am not pregnant but these symptoms seem to indicate a miscarriage? Any advice would be appreciated and i would rather not go to a doctor if possible.
