Bleeding for ten days

Hello everyone. So me and husband have been ttc for almost a year with no luck. Since ttc my period have been all out of wack, coming late, twice a month, lasting 2-3 instead of the usual 4-5. Well this time around I am officially on day 10 of bleeding with what seems like no end in sight. It’s medium flow not too heavy but also still dark red and not light pink like it’s slowing down. My old obgyn moved out of state and I’m currently waiting to get established with a new one (appt is on November 6th 🙄) so I contacted my family doc who just advised me to take a home test or to go to the er if I am going through a pad an hour.

Other than that I have to wait it out.

I took a home test on September 6th and again today 9-18 both negative.

Has anyone else had issues with period going crazy since ttc? Also how long should I wait before I ask for an US or other tests. I understand there’s no magic power that can make the bleeding stop but If I could at least know why this is happening I’d feel better.

TIA!
