Birth control and pregnancy

Kelsey • TTC rainbow baby! ❤️💛💚💙💜 I have two boys (6&4) I had a MC march 2016 and then a ectopic pregnancy June 2016!
I've been taking a birth control pill for a couple weeks now, I started taking them around 11am every day but the past week I've been taking it a few hours late. A couple days it was 10-12hrs later then I was supposed to. Last night my husband and I had some "mommy daddy time" and I hadn't taken my pill yet and I took it after we had "our time" that made it 10hrs late. What are the odds of me getting pregnant? Any advice on this will help. Send them my way please!
