So for the past 3 months I’ve been getting really sick during the week before my period.

My blood pressure gets super low out of nowhere, I start throwing up and feel terrible... it’s usually for a day or two but it sucks really bad

Yesterday I was feeling great the whole day and at night I started to feel sick, throwing up and all... and now I have this terrible back pain that feels like it’s because I’m feeling gassy but it won’t go away since last night?

Anyone also have this? Any tips on how to make it better?
