confused

I suffered a loss at 10 weeks in September. Baby stopped growing at 8 weeks. 3 weeks ago which was 4 weeks after my d&c I took an ovulating test. It was positive. 15 days later (today) I still haven't gotten a period. Negative pregnancy test today but have been experiencing ewcm yesterday and today. Got a positive opk. I'm going on 7 weeks no period since d&c and am worried I will never get back on track! Any insight would be great. Thanks :)
