Almost a month ago, I was mid cycle on my birth control pack. I got my period a week early which I think may have had something to do with the fact that I was living with another girl and my period started synching to hers. So, anyway, I got my period a week early so I did not have a period during the week of my inactive pills. My boyfriend and I had sex on day 4 of my inactive pills. I ended up starting my next pull pack two days earlier than scheduled. So I started my new pill pack on a Saturday when I should have started it on a Monday. I have taken my pills without fail since then. It has been 10 days since then. I have also been on a UTI medication for the passed 9 days. Online I read that UTI medication does not counteract birth control. Over the passed 2-3 days I have noticed that I have been having thick white sticky discharge. It is stretchy. Is this normal? Could I be pregnant? Please help.
