Confused please advice?

Is it possible to get a +OPK and then 10/11 days later have some small sharp pains where your right ovarie would be? It's only just started, happened about 4 times. I'm currently going off of my OPK to tell me when my period would be because in April/may didn't ovulated till CD31. And my cycles have always been long and irregular. 
​ 
​Back ground: got pregnant may 23rd CD31 ovulation confirmed June 3. July 12th miscarriage, didn't pass the "products of conception" until aug 2nd in hospital needed a blood transfusion, bleeding stopped about the 7th. Waited until I had a period sept 6th which was very light to start having sex again.
