What are my chances of pregnancy?

[GracieJames]

I came off my pill 3 days ago, and have had intercourse 3 times over the past two days as my libido has been SO high! I also had mild cramping and twinges in my left side like my body is preparing for ovulation. I've read ovulation can occur 48 hours after coming off the pill - I took some OPK's and they were negative but definitely faint lines showing LH is back in my system compared to the stark negative tests I took whilst still on the pill. I know it's probably very very very low but has anybody fallen pregnant like this before? Thanks!

As the LH strips are negative (they will always have a reading, but the line needs to be at least as dark as the control strip to be positive) then it's highly highly unlikely you have ovulated and so won't be pregnant. There's an outside chance it could have happened that fast and you peaked really fast and missed it on the strips, but I don't think you're pregnant from what you've said.
