I have not had my period yet and I don’t know why?

I have not have intercourse just grinding and fingering with my boyfriend, with shorts and underwear on, around October 29th. Then November 5th, for about 3-4 days, I had discharge that was yellow, light brown, pink, very dark brown long and stringy like snot, blood red, dark brown again with the snot texture, light brown, pink with a little blood, and yellow until it fizzled out.

I have taken 3 pregnancy test, early detection, one a few days before my missed period, a day before my missed period, and two days after my missed period. All were negative.

Also to mention I didn’t have no symptoms of pms or pregnancy. No cravings, no sore boobs, no going to the bathroom a lot, no nausea feeling/getting sick, no increase appetite. Just cramps and I’ve had a slight sore throat.

I’m 4 days late and I was dry a couple of days ago but now I’m having white discharge that’s like sticky and thick. Also now I’m starting to have pms symptoms like last night I had cramps like my period started but still no blood, I’m craving chocolate, increase appetite, and my boobs feel sort of sore

Has anyone ever experienced this or can please give me some insight on what might be going my on? I called all the OGBYN doctors in my area and when I describe my symptoms they ask if I’m pregnant and I say I haven’t even had intercourse. I’ve not had penetrative sex or anything. Then they say I need to see a doctor but they don’t have any availability till next June 2023.

Does anyone have any explanation…?
