so last night me and my boyfriend had sex and afterwards i bled quite a bit. To the point that I thought I should probably put a tampon in. It was weird bc it was not rough at all (tmi sorry). The bleeding is almost gone today, last night it was bright red and in abundance and today it's every now and then when I wipe after I pee and brownish. I am having what I think might be very early pregnancy symptoms (tired, nauseous, slightly crampy, headache, gas pains, burping, some what constipated) I took a pregnancy test the other day and it was negative. I just don't understand why I would bleed like that. If anyone has any advice I would love to hear it. Much thanks.
