Missed period then 10 day period

Ok, I hope this isn’t too confusing..

I stopped taking BC about a month and a half ago and we tried to conceive but had no luck the first month so I went back on BC after a discussion that our timing wasn’t very great to begin with (pending cross country move).

I missed my period the month BEFORE going off BC, then when I went back on BC starting with a new pack, I got my period a whole week before I took the “period pills” and it lasted 10 heavy days!

I’ve been suuuuper tired and emotional/moody and just have no idea what is going on. Maybe a hormone imbalance? Pregnant? Miscarriage? I haven’t taken a preg test yet. I told my husband to grab one on his way home from work.

Has this happened to anyone?! Any insight?!
