BFP after bleeding

Hi everyone!

I started bleeding at 9DPO and thought I was starting my period early. However, it seemed to be on and off so I decided to take a pregnancy test. I got my first faint line at 10DPO and then tested daily (sometimes twice daily) after that. I bled on and off for about 3 days, lighter than a period but heavier than spotting. I assumed it was a chemical pregnancy but I’m now 15 DPO (bottom test) and the test line just keeps getting darker. I have an appointment with my doctor next Monday but I need some reassurance that things are looking good lol the bleeding really threw me off! Has this happened to anyone else? And did things turn out okay?
