post <5 bleeding

Hi all! I’m wondering when your cycle “evened” out post ectopic/MTX.

my timeline:

11/24- positive pregnancy test

12/7- bleeding. went to ER & discovered ectopic. HCG 526. MTX given

12/9- HCG 896

12/13- HCG 517

12/27- HCG <5

my OB unfortunately did not follow standard blood draw protocols following MTX so those are the only HCG checks I had. fortunately I guess, we got to <5 with just one dose of MTX anyway.

I bled for exactly a week after my MTX shot (12/7-12/14.) then started bleeding again 12/30-1/3 (which I thought was my period since by that point I was considered not pregnant) and now, 1/11, I am bleeding again but it is very dark brown blood. I’m so confused by what’s going on in my body and just feeling very frustrated with this whole thing.
