Postcoital bleeding.

Vicki • My husband and I have been TTC baby #1 actively since February `14. Love and baby dust to everyone!
My husband and I BD'd last night, nothing any more exciting than usual, and this morning when I wiped it was pink. I held some tissue to myself for a few seconds and there was a very small amount of blood.
​I'm not due my period for a week and I'm pretty sure I ovulated last week!
​Not too sure what's going on. I'm not having cramps or anything, has anyone got any ideas or experienced this?
​Thanks for your help!
