Cramping & spotting after BFP

Hey ladies - I’m a bit worried rn, so I was hoping to get some insight. I’ve been experiencing spotting & cramping on and off since around last Sunday (sixth day now). Every day pretty much this is happening.

I got a BFP yesterday.

The cramping is mild but definitely noticeable during the day. And my spotting has gotten a bit more substantial - not enough for me to feel the need to put on a pad. Color is rust, brown, or light pink/red.

AF is due in 2-3 days. I can’t get to a doctor until the first week of Nov, since I’m out of town…

I thought my implantation period was over & this stuff was supposed to stop?? Anyone else relate to this?

Is this possibly a miscarriage about to happen? Even after getting my BFP, I’m thinking it’s strange. BUT I’ve never been pregnant before so I’m not sure what’s normal & what’s not.

Thanks for any tips or personal experience!
