Spotting brown again, no AF - another ectopic?

Hi guys, had EP tube removal surgery last nov at like 5w.

I’m currently 2 days late for my period but spotting maybe once or twice a day when I wipe and it started off pink yesterday and now brown. Most other times I’m completely clear.

I remember with my last EP I had 4 days of spotting before i got a BFP, similar to now.

Yeah I’m just worried. Can healthy pregnancies start like this? If not - where is AF...testing again tomorrow morning if no AF...
