When to test after miscarraige

I miscarried on 7/7 bleeding till 7/14. In between 7/14 and 7/28 (bleeding started again, but don't think it was my period) I was taking opk's and got a positive surge on 7/19. After the bleeding stopped on 8/3 I started doing opk's again and have not got a positive surge. I have felt slight twinges within the last week and my boobs feel heavier than normal. Should I take a pregnancy test or what do you recommend?
