Depressed

Heather
I don't know what to do, scared that it will never happen.
I've only been off BF for 4months and I was on it for almost 6years!! 
Before that I did have surgery on my overies cause of cyst and the doctor said then it could be an issue with me having a child but a year later I got pregnant with my daughter who's now 6. 
Since I've been off my BC I still haven't had a period, not sure if that's normal or not.
I just don't know what to do because this is making me upset taking ovulation test and pregnancy test too.
