I had a leep procedure done back in February 2015 and now my periods have been irregular. Which is very weird because before this i knew exactly when i was suppose to start.

My boyfriend and I don't use condoms but I'm on the pill which I've been taking off and on for the last 4 months.

I had my 1st period within days after my leep procedure.

My 2nd period came almost 2 weeks early and I spotted (only when i used the bathroom) for a couple days.

My 3rd period which i had on the 21st was almost 2 weeks late and I bleed the 1st day and spotted (again when i used the bathroom) for 2 days afterwards.

I took a pregnancy test the beginning of April and it was negative. I haven't taken another one since. I know stress, hormones etc can cause your periods to be out of whack but any idea as to what i should do to regulate myself out again??
