Kinda scared

So I just used the restroom and this was on my underwear. I’m kinda scared because a big chunk came out of my vagina; I saw it using the front camera of my phone. I cleaned myself up and put a underwear liner on. I’m kinda scared because this has never happened to me. I’ve have normal cm but not like this!! It didn’t smell like anything. My urine smelled like penicillin because I’m taking some for a tooth infection, I’m on Yaz the birth control pill, and I’m taking collagen but that’s about it.

Update: I ran off to Walmart and bought this! Is this good enough? I don’t any itching or anything. Should I continue to take Penicillin or stop? I’ll make an appointment with my doc on Monday.
