Trying to conceive!

This is the first time I’ve ever posted anything this personal! I got my implanon out in November 2017. We immediately began trying! We haven’t stopped trying. My periods have been 3 days. The first day being actual period and other two days just the nasty discharge. It’s been like that since November when I got the birth control out. I do have a 6 year old son and I had no problem getting pregnant with him! I had him in April 2012 and been on the implanon ever since. It’s been almost a year and I don’t know what to do. We aren’t done trying. But I just want another baby! Well we want it! I don’t have any insurance to get the proper tests done. All I have is the family planning Medicaid and they only cover my paps and birth control if I want it. But I’m lost for words. Our son wants a sibling so bad. And we are so ready to give him one. 😔
