Needing some help

Chloe

Hi everyone, so my periods have always been painful so I started the pill. I came off of it about 4 months ago and my periods are even more painful now. Last month I bled for 2 days, and it was closer to spotting then bleeding. This morning I woke up to spotting again and I have been in the worst pain, throwing up and almost passing out from the pain. Also, it isn’t red like blood, it’s watery and brown. I have every pregnancy symptom apart from missing my period but tests are all coming back negative.doctors can’t make an appointment until 9th December at the earliest and I’m starting to freak out because me and my partner have been TTC since august. Anyone have any idea what could be going on? Thankyou💜
