Help please!!

So I have been late 7 days now I tested when I was 4days late and got a negative test now that I'm 7 days late I feel super sick nauseous like crazy Even when I'm in bed laying down 😷 so today my so and I had sex sorry for too much info... And a bit later I got the urge to pee when I went I noticed pink discharge on my panties as I wipe I said ok so I'm not pregnant I started my period.. well turns out I'm not bleeding anymore and when I wipe it was just a bit of blood mixed with thick clear discharge I feel confused can it be my period starting or can I be pregnant. I will be testing tomorrow morning I just want opinions from you ladies thank you.
