What period!?

Wow.. haven’t been on here in forever! I had my first baby 6 months ago (he’s the best 😍). Any who... I had him in March and my period started for the first time August 26... well, it’s October 9th & no period 🤷🏼‍♀️ I’m breastfeeding my little guy and obviously my hubby and I are sexually active. No birth control but we use condoms. I’ve read that when your period starts back up it can be wacky & how breastfeeding can also throw it off but I guess I just want to hear stories.. also I know that I can’t know for sure unless I take a pregnancy test. But, I just remember how much a help everyone was during my pregnancy so just seeking help now! Thanks in advance!
