Light/medium bleeding between two periods.

This is a first for me, but l've been bleeding nonstop since December 8th, 2023. It's very light but it still makes me worried. I'm 18 but I had my period when I was 10-ish.

I'm taking birth control (Vestura) and this is the first time this has ever happened to me. I was on Junel before for almost a year. Never had something similar to this happen.

I do have a boyfriend that I’m sexually active with and we do not use condoms.

I started my Vestura in August of last year after not being on birth control for about a year. Because I know that can be important to know.

Thank you so much!

Forgot to add that I’ve been super nauseous and the thought of food has been making me gag.
