Im 20 ys old and was on birth control for two months then the thrd month i forgot about taking it i stopped the pill.i have been sexuallly active for about 2 yrs now and it wasnt until college that my periods were irregular more frequently. dr.s have said could be bc of stress or std or pregnancy pregnancy and stds were ruled out after testing. so the last time i had my period was last month july 19-25 the first three days were really heavy and i had no choice but to use tampons -playtex gentle glides the super absorbency fresh scent ones. I usually never ever use tampons at all. now its aug. 8 or 9th and i have my period? but it came with cramping no signs like spotting it just arrived and wasnt a flow yet but enough blood was there that it wasnt merely spotting. after my period july 19 was over, my bf and i had intercourse and it hurt. he couldnt really go in bc it was too painful we've attempted several other times, and still painful the last time we had sex about a week ago it hurt and it felt like i had to urinate as i climaxed? it kind of tingled or felt sore to the touch I do not know why but "it" refers to inside my vagina like on top is where it felt sore that even now two weeks later i sit and i have the same sensation. after sex it burned a little from peeing it is from holding it in as to not ruin a climax? i have had a uti from taking more than a weeks worth of anti biotics back in may- june and this feels nothing like that. could it be from dehydration due to a heat stroke i had on aug. 5th? or from using tampons during my last period?(i forgot to mention that i used a super absorbency tampon and it got stuck bc there wasnt enough blood i got into the shower and had to wet it first before successfully but very painfully ripping it out, could the soreness and pain/tingling be from when i ripped out the tampon? is that why sex hurt after that period? bc it feels like the same pain i had when i removed the tampon. could the reason for my early period be because of left over blood from my last period due to tampon use? or could i be pregnant and having a miscarriage since i stopped birth control?
