Ovulation confusion ??

Benita
So Iv been taking ovulation test for 11 days the first day the test line was the darkest I had so thought I ovulated early , been getting 2 lines the whole time but not postive , I'm sure I ovulated on Thursday been got symptoms you get like cramp / pains and the cm changed , continued to take ovulation tests still no postive ? Got a postive today ? Do you think I am ovulating late ? I misscarried around 5th Feb , Iv had a period since tho . Just after some opinions / help please ???
