Spotting after orgasm

Ca

So I’m 5.5 weeks and this is my first pregnancy! Long story short Sunday night me and my husband messed around (no sex) and I got off. Well then I went to pee and wiped and noticed some light pink spotting. Freaked out went to the ER and everything checked out to be fine. Got my hcg levels tested and Monday they were 973, went back Wednesday to redraw and they were almost 2,000. Dr said spotting was normal and I’m not having cramping with it! So I’m relaxed not panicking anymore well this morning again i “got off” and went to pee now I’m spotting again!!!!!!! Like it’s only happened when I’ve had an orgasm! Has this happened to anyone else? And yes I know I should ask my dr but I called and left a message so they will get back with me on Monday so in the meantime I’m asking y’all for advice.
