Day 15/hypothyroidism

Seren • I have a beautiful three year old daughter and am currently trying to conceive baby number 2 ❤️
Hi! It is day 15 of my cycle and according to the OPKs I have not ovulated yet this month and according to glo my fertile period has now ended. When I got pregnant with my daughter i ovulated a week late but luckily took a opk. Does anyone else have this and could it be connected to hypothyroidism? Fingers crossed it happens this week. Thanks x
