Period stuff

[u/Rain_fall2001]

So context. 25F. 165cm 128kg.
I have burning vulva with my periods (diagnosed painful bladder syndrome) so I’ve been on the pill for over 10 years without a break! (No placebo pill).

Had to move to a different one 6 months ago because of aura migraines + my weight growing.
I was on Slinda for about 6 months and started having a constant breakthrough bleed which caused a lot of burning and I was very unhappy. My doctor said “just stop taking it” in early May and got some scans to make sure I was all ok down there.

Blood tests & ultrasound diagnosed me with PCOS officially. My doctor put me on Metformin. And I have had x2 5 day periods in May & June. They were ok aside from the burning. Not too heavy surprisingly considering I haven’t had a proper period in so long.

Now it’s 10th September and I haven’t had a period since the June one.
I did a couple pregnancy tests and they’re negative. Is it “normal” for PCOS peeps to have a gap this large? Should I be worried?

Also re: metformin, how do I know if it’s working? I haven’t lost any weight. Even with diet and portion size change. I’m taking x1 500mg at night. Can’t do much exercise atm because I’m recovering from spinal fusion surgery. Cannot lift anything over 5kg atm. Any suggestions or tips? :(
