hi,
I've been on cereal since last August and my cycle length has ranged from 47 days to 38 days but recently its been in the 38-41 day range. This month I had unprotected sex (only using mini pill) on cycle day 11 and had brown spotting/brown cm on cycle days 14-18. I have been having really bad cramps the past week and felt like I was going to come on. I am on cycle day 49 and have taken three pregnancy tests since cycle day 45 all of which were negative. Could I be pregnant? Or is this just the mini pill? I really don't want another baby right now
