When can I test for ovulation?

Pa

Here’s my tests from this morning. I am 2 weeks post miscarriage on 1/18. Missed miscarriage at 7 weeks found out and passed them at 10 weeks. My hcg line is super faint but still there. I was wondering if anyone was able to actually test for ovulation while still having hcg in their system or during the first cycle? All of my opk tests have shown positive since a few days ago. Worried it going to miss it lol. I stopped bleeding yesterday.
