Periods after birth control...

Got off the pill October 18th. Didnt get my first period off the pill until Nov. 29 (like 44 day cycle) i ended that period Dec. 5 and now on January 12, I havn’t had a period since Nov. I was regular on the pill but now it doesnt seem like it. I test as much as I can with opk but during the week I got my highest I was out of town and couldnt test. So i assume I missed my surge with opk.

I have taken many hpt and all negative:(

My husband and i have been trying since October but I’m not sure wht to expect with my ovulation and/or period. Any thoughts? Similar stories?
