Clomid increasing chance of pregnancy (while on BC)

[hit_it_hard]

I am in pct for my cycle, on 50mg of clomid a day with 20mg of nolva. My girlfriend is currently on birth control, but I was wondering if by me using clomid, it would decrease the effectiveness of her birth control preventing pregnancy. Tried to search on google but had trouble finding anything related to male (bodybuilding) use of clomid. Thanks for the help in advance.
