I gave birth over a month ago and my cycle has not returned yet. I had intercourse last week and used an emergency contraception pill, Levonorgestrel. Being a pleb, I had a few drinks yesterday and had unprotected sex. I have just read you can take 2 emergency contraception in the same cycle, however it may cause irregular periods. Would it be okay to take a second one baring in mind my cycle hasn't returned yet?
