Ovulation after MC 😭

Melinda • Had 4 miscarriages in 2015 and had our rainbow baby December 2016
I miscarried super early into my pregnancy Feb 24th. Baby stopped growing at 4 weeks (according to beta levels) and miscarried when I would have been 7 weeks naturally. We got the ok to start trying again a week later because my levels returned to normal. I then started to use OPKs to track ovulation because my dr said my cycle might get thrown off from the MC. I never got a positive opk. In fact, the second line was almost never there. I finally started spotting tonight. We bd every other day just in case I missed it. It's been a super stressful month. We moved and a lot of other stress with my husbands ex wife (wanna be mother to his kids). Could the stress cause me not to ovulate? Is this normal without the stress to not ovulate after a MC?
