In the name of Allah, We praise Him, seek His help and ask for His forgiveness. Whoever Allah guides none can misguide, and whoever He allows to fall astray, none can guide them aright. We bear witness that there is none worthy of worship but Allah Alone, and we bear witness that Muhammad (saws) is His slave-servant and the seal of His Messengers.
Basically sister this is a medical problem and you should consult a physician.
However, for the sake of making yourself available for namaz, you should refrain from salat for the regular 4-5 days and after that if no blood is witnessed you should make ghusl and start praying as normal. If you witness some watery blood after ghusl, then wash your private parts thoroughly and wear a sanitary napkin, make wudhu and offer your prayers.
Whatever written of Truth and benefit is only due to Allahs Assistance and Guidance, and whatever of error is only ones. Allah Alone Knows Best and He is the Only Source of Strength.
