I’m so confused, chemical?

[Jprpl]

Hey, I thought I was having a chemical as I had a faint test at 15dpo. Then at 16dpo (today) I started bleeding but I’m test now looking darker again. What could be going on? Still bleeding, but very light mainly dark red/brown when wiping and not filling a pad. Only slight little cramps

16dpo test is still wet so may dry darker

Implantation bleed ?
Twins?
I had similar and I had erosion of the cervix but the pregnancy was uncomplicated and had a baby boy ❤️

I'd be calling epu if I were you, and getting them to check for an ectopic just incase.
Or it could just be a fluke on day15 and youre somebody who bleeds during early pregnancy. But rather safe than sorry x
