I had my period 2 weeks ago, on Monday morning I woke up and 1 hour after I had woke up I felt a wet patch in my pants so I went to the toilet and there was a lot of brown liquid in my pants? I didn't think much of it then I became really dizzy and felt really sick, but before I had noticed this 1 week after my period I had been waking up every morning feeling sick or having a really sore stomach. but back to this week, I have either been bleeding red or having that brown liquid? just in little patches like spotting's. I've been having really sore stomachs since this and really sore lower back pains. also I had sex with my boyfriend on the 14th of June so a week before my period? and again on the 28th so a week after my period? can someone tell me what's wrong? thank you!!
