Hi My Name Is Crystal I Was On The Depo

Hi my name is crystal
I was on the depo shot for three months and then went on the nuva ring.know my hormones are messed up. I have been bleeding for 6 months it slowed down alot. Me and my husband has been using the pull out method. My stomach has gotten big, I get sick smelling certain foods. My breasts has gotten a little bigger. I can't stay in the heat even when it is 70 something degrees. And my back has been hurting. Could I be pregnant
