Spotting at 8 weeks...

So I had intercourse with my husband this morning and ever since then every time I go to the bathroom I have light rusted brown blood on the tissue. It’s very light and more spotting than constant. Is this normal to happen at 8 weeks pregnant? I haven’t experienced any spotting or bleeding in the weeks before. I’m just so worried and my mind is running a million miles an hour just hoping that nothing is wrong with my rainbow baby.

Thank you to everyone in advance!
