5 days in a row of +opk and temp spike

Hello! I have been using opks and have now had my 5th day of testing in a row where the test line is as dark as the control line. I have certainly read a lot of conflicting information on the Internet. I had a miscarriage on May 28, the cycle following that was 38 days long, when my normal cycle is 28 days ( which is normal since they say not to expect your first cycle after mc to be the usual). Glow and another app have both predicted ovulation for me on cycle day 18 and 19, now cycle day 22 and still receiving positive opk. I have seen a temp spike so I'm pretty sure I have already ovulated. Any thought ???
