serious question !

Theresa • Due February 2017. second pregnancy, stepdaughter, fiancé. last year I was the 1 in 4. Praying my rainbow is healthy💞
After I had sex with my finance last night I went to the bathroom and wiped & saw blood! It wasn't enough to fill a pad up but it was still enough blood. Called doctors she said its normal to spot after sex but has it happens to anyone else but me???
