I had unprotected sex on day 8 of my menstrual cycle. Normally I have had a regular cycle - 31 day menstruation with a 17 day ovulation. Unfortunately earlier this month I had an ovarian cyst rupture (my period was 4 days late and had it checked). I started my period almost immediately after.
I had unprotected sex on day 8 of my cycle as mentioned before. 40 hrs in, I took the Plan B MAP. I took the first pill 40 hrs in then the next pill exactly 12 hrs later. I am fearing pregnancy. I have been off of BC for 5 months, but decided to take it again today fearing ovulation. I am tracking it via ovulation strips. I think Im due to ovulate in 48 to 72 hrs.
Will the extra birth control in the system help???

Day 8 would be a very unlikely time for ovulation and conception. Not impossible, but highly unlikely.
You cannot rely on birth control starting today preventing ovulation. It is recommended that if you start mid-cycle you use a back up plan such as condoms until your first period because they are not considered to be reliable for the first week you take them. If you ovulate within that week, starting them now may or may not help.
Once you are on the pill regularly and taking them faithfully, plan B would not be needed.
