No LH surge after miscarriage

Hi all, I miscarried mid-December at 11 weeks. I got first period over 3 weeks ago which lasted about 8-9days. I used opk before that period and got almost positive result. This cycle I also got almost positive result but never really a peak which is unusual for me. I always had my peaks and never got a problem with catching them. I randomly take my temperature too and it didn’t really went up as usual. I believe I’m not ovulating 😔 what can I do? Anyone with similar experience? Did it come back to normal and when? We’re so determined to try again but now my body is failing 😔
