Period and breastfeeding 🤔

So my daughter will be 15 months old and we are still breastfeeding. I haven’t had a period since the last missed one when I got pregnant with her (Jan 8th 2017) even though it has been pleasant to say the least, I’m kind of in limbo in terms of avoiding a pregnancy or even ttc (we don’t want another baby just yet but we will in the future) no idea if I’m ovulating or not, if I am indeed ovulating I have no idea when it’s happening. I am taking the mini pill to be safe but sometimes I do forget to take it 🤷🏻‍♀️ any other mom in my situation?? When did your period come back?? Every time someone says “are you sure you aren’t pregnant” (if I feel sick or my skin is glowing lol) i have to take a test cuz I honestly don’t even know!
