Chemical pregnancy

The last day of my period was January 31. In early March I tested positive for pregnancy. I had light bleeding/spotting. I ended up having a chemical pregnancy. I still have not had a full period. 
Has this happened to anyone and did it take a while for your cycle to get back on track? I tracked my temp and it is all over the place. According to Glow I am on day 38 of my cycle which is long! We did not try this past month as I wanted my body to "get back to normal" any thoughts?
Thanks.
