I am 43 and my period has always been regular, My last period was August 1st to the 4th, I had sex on the 7th, 8th and 9th. I ovulated on the 12th yet i started bleeding 5 days before my period is suppose to start. the first day it was light pink and spottie then it was heavy red and brown and then it was just red. it lasted for 4 days. What is going on with my body. Can I still be pregnant? Was it implemetation bleeding or was it an early period?
