Spotting vs Miscarriage

So I’m 5w5d i has a miscarriage in February but i was already having a miscarriage by the time i found out, due to me bleeding for 2 weeks before going to the doctor(my periods are irregular that’s why i waited so long).

This time i found out at 4 weeks and i have been doing fine with no bleeding until i was constipated and strained a little i seen some spotting then it was bright pink but after a few hours it stopped

Today me and my boyfriend had intercourse and a few hours later i had the same light pink spotting.

I don’t know if i should be worried and go to the hospital or if i should just wait to see what happens i have my first appointment 10/15.

Am i overreacting, or should i be concerned?...
