Day 3 spotting 6w 1d pregnant

I posted yesterday about how my s/o and I have intercourse and I’ve been spotting. First day for an hour and a half. Second day for 4 hours. Today it happened again for about 2 and a half hours. Has this happened to anyone else? It was light pink the first two days. This morning it was a red with small stringy clots then turned into a light pink again. It’s stopped for now. I just need a peace of mind. It’s been stressing me to the max.
