Pregnant or miscarriage

Hi!

My period is usually like clockwork! I can literally pinpoint it to the time it’s going to happen. We have been ttc for 2 years.

My period came 3 days early, obviously abnormal for me and was heavy but only lasted 3 days (normally I’m super heavy and last for 5)

Is it possible to be pregnant? Or could i have miscarried? Or just general AF?

According to glow i am due to ovulate in 5 days but my ovulation tests are faint positive.

Am I reading into this too much!
