HELP!

In 2006 I had my 2nd (last) baby. I got an IUD put in and got it taken out in 2010. Didn't try to prevent having a baby but wasn't trying to either. 2013 got married to my husband never tried to prevent having baby but wasn't trying to either. Well in Oct. Of 2016 I had weight loss surgery. Nov. Of 2016 I got a Depo shot. I was suppose to gotten my 2nd shot in Feb of 2017 but in Jan. We decided we wanted to try for a baby. We don't have kids together. He has 2 girls in a previous relationship and i have 2 boys in a previous relationship. So we would like to have a little one together. I didn't get the shot in Feb. Had my first period at the beginning of March and then again at the end of March. Then again in 2 weeks after my period in March. Not sure if this is cause of the depo shot or not. I just started taking Folic Acid, Geriotl and conceive easy Advanced Conception.. trying every way I can to have a baby... so my question is has anyone else experienced this or something similar to this that could give me some advice or even had a success story... Thank you!
