Postpartum periods

My son is 6 months old and my periods have been coming on the exact day it says they would. I've also been ovulating on time like I should. This app hasn't failed me in 3 months! I'm wondering if its normal for my periods to go from being super irregular to regular after having a baby? My cycle was so irregular before I had my son that it took me and his dad 3 1/2 years to conceive him. But now it's completely different!

When I ovulate I don't even need to take a test like I know when I am because my discharge increases significantly to clear and stretchy. I also get subtle cramps. All right in the middle of my cycle. I'm happy that I'm regular now because I feel like conceiving our second baby should be easier 😁
