Had sex with my boyfriend 2 days before my period ended last month and i let him come inside for the first time coz i read it was safe. Had sex in between and we only used the pull out method. I had my period for this month 3 days ago and it was unlike my usual. First day was heavy in dark color with brown tissue-like discharge. Second day became instantly light and on the third day, there was no more discharge the whole day but inside my vagina, there were dark brown that’s like cottage cheese inside and i can’t say it was only little. Until now there is still few i van get inside and its worrying. Is it possibly a miscarriage or due to too much stress last month? Pls help.
