@Sarah I track BBT and have quite clear ovulation symptoms.
Symptoms of ovulation and periods can change post pregnancy. Have you tried tracking with ovulation strips? If not it may be worth it
I don’t ovulate at all while breastfeeding but I also don’t have a period at all bc of that. It’s unusual to have a period and not ovulate but I would say if you want to get pregnant you might need to wean 100%. After I wean it takes about 1.5 months to get back to normal.
How do you know you aren't ovulating?
