What’s “spotting”?

Last weekend I had the tiniest amount of baby pink color in my discharge. I let them know. We did hcg (11200 at 24 dpo) and because it was so high, I think they doubted my ovulation date (which is unmistakable w how my LH surges) so they had me do an tvus at 26 dpo. Empty sac in uterus which is totally normal so early. But w the ‘spotting’ and the (what I described as) occasional pangs that sort of feel like ovulation pain, they told me not to rule out a second ectopic going on.

The night after the tvus I had some blood mixed in w my discharge which I expected due to irritation. Now two nights later though, I’ve got that same barely baby pink creamy discharge. The pangs are intermittent but frequent enough.

Anyone had similar symptoms? I’ve read some color occasionally is normal but then on other ectopic pregnancy symptom sites, am reading ‘pink discharge’ and ‘pangs’ can be symptoms. I would think an ectopic pregnancy is more painful? More obvious? Is it normal to have the small amounts of baby pink over time?

I know I have to wait to see if the pregnancy in my uterus is viable and only time will tell. Is that true for my own safety too? To rule out an ectopic??
