First period 7 weeks PP

Hey ladies! So I had my daughter on Aug 10th. Had PP bleeding for roughly 3 weeks after a smooth vaginal birth. Then I had Lochia, different type of discharge, for a week or so....everything finally stopped. AAAAANNNNNDDDDDD then...boom. Aunt flo shows up.

I dont have an issue with it starting. Kind of glad it did. But here's the thing...I breastfeed and pump and will occasionally supplement with formula. We're talking no more than 3 bottles a day.

I find myself being a little irritated and frustrated more often. I never had cramps before I had my daughter and now I do...and I'm miserable. I'm not sure if I've seen a difference in her reactions towards me or her moods change besides what's been normal for a few weeks now.

So with that being said... how many of you had aunt flo show up shortly afterwards? Did it affect your mood and or breast milk? Did the baby react to you than s/he normally would? Are your cramps less/more intense?
