I’m stressed like crazy.

So I am 10 months pp almost. EBF. I use to be able to pump up to 5-6oz per breast. My husband went away for two months so I strictly just fed her via breast instead of pumping for a bottle so my husband can feed her sometimes. I also quit my mini pill while he was gone in hopes to have a regular period because I only had random break through bleeding since 5 months pp. Two weeks after stopping the pill I got a full period and the month after. I started my mini pill back up a week before my husband came home. I feed my daughter via breast throughout the day till her bedtime around 6-7pm and then try to pump around 9-10pm before bed. However.. my supply is 1oz for 20 mins!!!! That’s a HUGE pumping drop for me. My period have been irregular my whole life and this will be my first period since back on the pill and technically according to my app I am two days late. Light cramps and negative home pregnancy tests. My girl is constantly wanting the breast. I’m scared that my supply is fading.. i don’t know if it’s cause my period is trying to come, stress, or her going through a growth spurt but I’m so stressed. I need some advice or positivity. I feel like a crap mom.
