So I decided to change my start day on Ortho tri Lo from Friday to Sunday..after about a year. So I started my period late..its usually around tues. or weds. but this month i got it on Friday. Well I decided to change my start day from Fri to Sun..Now, am i supposed to use a back up method for a week..or will I be protected since I started my period on day 3 of my period? I think that Planned Parenthood told me I could start taking the pills up to 5 days into my period..I don't remember if this was for ortho tri lo, or for some other one that I was on for a bit and didn't like. I believe it was Cyclessa. This was like a year ago.

Anyway, so bf and I had uprotected sex and I was wondering if i should take Plan B, and just continue like normal on the rest of my pills??
