Tmi mention of blood

Hi my periods are short. Cd1 and 2 I bled but cd3 typically only stays inside my vagina and barely anything comes out besides maybe very light spotting. Yesterday I checked and clotty jelly like brown so figured over. Today I checked near my cervix for tracking purposes and small amount of stringy brown mucus( cd5 )

Then I checked again and saw VERY small amounts of bright red mixed in with some mucus. I always start period with bright red but never AFTER period turned brown and is OVER do I see return of bright red. I'm very scared. I have not had sex in 2 mos but posted my question here bc typically general ttc are very knowledgable . Please help I'm scared 😱

Also I check my cervix area to track my cycle
