6w/4d need advice

Last night I had some mild pink blood when I whipped. About 2 hours later I went back to the bathroom, more pink. When I got up to flush there was a small blood clot floating in the toliet. It was almost like a period blood clot (like when you first start, and they're small and stringy looking.) I was a little worried, but decided if it was still an issue when I got up this morning I'd call my OB. I have been up since 6:30am and I've only noticed light brown spotting. Is this normal? Is everything okay? Or should I call my OB?

NOTE:

I am in Kentucky, I found out I was pregnant with a home test around 4w/5d. My pregnancy was confirmed at the health department on 4/13 at 5 weeks.

My OB won't see my until 10w. I go for my first appointment on May 20th. I will be 10w/1d
