On the night of the 21st i had intercourse. The next day in the morning i went to the bathroom and nothing but blood came out. Then i started having cramps. Bleeding got more heavy, soaking tampons every 3 hours maybe less. Today i woke up with blood on me, and a huge spot on my blanket, but I didn t have a tampon or pad on because it slowed down a little. I had pain on one side then the other, sometimes both. What should i do.?
