What is this? Gross pic (sorry)

[EternalSunshine19]

I went on the pill (Microgynon) at the end of October and I've ran packs together.
i thought i had BV on Wednesday due to smelling fishing for a few days even straight after a shower so i bought some branded BV gel and have been using it since yesterday when i suddenly got a period.
I thought it was weird to get a period, but thought maybe it was a breakthrough bleed.
today i went to the toilet and noticed this flesh like substance on the loo roll once i wiped.
what is it? Sorry for the gross pics

Sorry I can't help but hope you get sone answers it's very unusual looking. Definitely make a gp appointment tomorrow

I think its called a decidual cast from other similar threads.

Maybe a large fibroid?

a piece of tissue that you pass through your vagina in one solid piece. It happens when the thick mucus lining of the uterus, called the decidua, sheds in the near exact shape of your uterine cavity, creating a triangular “cast
From Google ^

I had something very similar once and never again - I would say it was the size and consistency of a small chicken breast. Don’t know what it was but it was years ago and never happened again and I’m fine.

Thank you everyone. Yes definitely going to make a doctors appointment tomorrow. I don't feel so panicked about it anymore after reading these replies, so thank you 💐

These pop up every so often on Mumsnet and are deciduous casts as said above. I'd never heard of them until I saw them on here.

I knew what it was even before opening the thread! Lots on here over the years.

Just a pity it's not a period in one go. That would do me.

Yes looks like a decidual cast. I've never had one but apparently they are very common if you take the pill and are not anything to worry about!

Yeah, decidual cast. I had one this year after Covid, freaked me the fuck out!

This.
