Brown Periods -Help!

[sophie19]

I started the combined pill when I was about 16 years old. I’m now 30. While I was on the pill, my period changed from looking like a normal blood flow to going completely brown with no red hints at all. I went to the doctors and was told this was completely normal and was due to the pill. I came off the pill last year, but my periods have not returned to normal, they are still brown but slightly more runny. I have contacted the doctors who have booked me in for bloodwork and swabs. Has anyone had a similar issue and been diagnosed?
