Hey girls!

I’m going through a bit of confusion right now and here I’ll explain why and hopefully you guys can give me some ideas/answers

So I was on Depo for a year and 2 months. I got off of it in January. I never went back for my January shot. I went to my doctors a few days later and told them I wanna be off of Depo completely cause unfortunately I’ve gained a lot of weight with it and I’m not too happy about it. But anyways I was told I’ll get my period in feb since the Depo was out of my system. Welllll it’s April and I haven’t gotten my period. I had unprotected sex a few times so I took a test just incase but it came out negative 😕

Can anyone tell me what’s taking my period so long ? Sorry for the long story but just wanted to give all the details
