K
Hi ladies. Im currently 11 weeks pregnant. Yesterday i started spoting brown blood. And after couple hours it stopped so i went to er and after ultrasound they said everything is fine. But now when i whipe i see brown spoting on toilet paper (sorry tmi). Im so worry that it will end up dont wanna say rhis world:(. By the way had intercourse just the day before spoting. Can intercourse give that? Or what could it be. Do u ladies experienced something like this.
