I’m just lost.

So all of my apps have my period starting between the 6th and 9th (and one on the 4th) and my first day of my last period was December 1st....I had been feeling really off so I decided on the 28th to test and I had a really faint line positive. Tested today and still very faint. I’ve had three losses in the past two years and my last loss the tests were this light and I’m just lost. I don’t know when I could have ovulated or how far along I could be and that maybe I’m just so super early that it’s ok to be this light still? Anyone have any insight? Any wisdom? Thank you!
