hi. i have been sexually active the month of july and i had unprotected sex all the time i got my period in july on the 17 and now i am two days late and i feel weird...earlier this week i had some cramps but havent gotteen any today. and this morning i went to the bathroom and when i wiped there was some brown discharge on there and after that i went again twice and a lil more came out but not anymore. i am really worried if i can be pregnant.. should i take a test now?
