Bleeding after sex

Jerayskin

Hey ladies, I have had 2 SCH in this pregnancy, the first may have not completely gone away but I was told that if had. The first was at 7 weeks and the second one was at 13 weeks. I've been to the dr 3 times sine the last bleed and was reassured that it was completely gone. 

Last night DH and I had sex for the first time since December.  I woke up this morning to some dark red bleeding and it really has me worried. I haven't soaked through a pad yet but it does gush when I sneeze.

Has anyone had this much bleeding after having sex? We were really gentle but I feel terrible! I'm going to call my dr in the morning, I was just looking for some reassurance. TIA
