Anyone dealing with the same struggle?

Hey guys!

Ive been trying to get pregnant for 6-7 months now. I got off the depo shot in july and I understand it takes time for it to get out of your system but the thing that has me concerned is that my period has not been coming monthly. The last time i got my peirod was back in December. Its been weird, it will skip a month then come skip another month then come. Im just wondering if anyone who was on the depo shot for about 5-6 years had any of these issues? My Gynecologist says that its a normal thing but it just feels too off for me.
