Weaning side effects

I started weaning my 1 year old, and have dropped 2 breastfeeding sessions in the past month spaced out about 2.5 weeks in between. Lately, I've been having symptoms that I think are related to the weaning hormones- nausea, fatigue, headaches and hair loss. I'm not pregnant, but I feel like I'm in my first trimester again! Should I slow the weaning process down, or should I just push through?
