Flu symptoms

LeeAnn • Mama to 1 and pregnant with our Rainbow baby.
Dd is 17 months old and we are TTC. My periods have finally became normal agian, but for the past few months, right before I start and continueing for my whole period I feel like I have the flu! Nasuea, chills, sweats, extreme fatigue, and diarrhea. Has anyone experienced this along with there period? It's awful and I'm so tired of it.
