Life after the Depo

Brittany • I am 26 and my husband is 28. Newly married in may 2015. I am a special education teacher and my husband works with lawn care.
I stopped my depo shot after my April shot due to me and my now husband wanting to try for our baby. Since then I got my period back in August and I have gained 30 lbs even though I watch what I eat and cut out soda. Has anyone else had this?
