Advice please ❤️

Hey ladies! So I'm new to this app! And I'm trying to conceive with my fiancé. We have a 6 year old daughter. I just got the nexplanon out of my arm a month ago. My periods have never been Normal the last one I ever had was march. I'm worried we're not able to have a child. We tried last year for a whole year and nothing also. I've been on many different birth controls since my daughter was born and I'm just terrified.
