Bleeding while pregnant..

andrea • Genesis Lucia Lechuga 💘 Our princess due October 28th 👑 FTM. 19 years old.
I'm 6 weeks pregnant& I have Just a few questions,
Is it normal to bleed after having intercourse? 
If so, how long should u bleed for?
My SO and I had sex earlier for the first time in a couple of days and I started to bleed in the middle of it (kinda embarrassing, but it was all good, he didn't mind) when I wiped, there was a small red blood clot & what seemed to look like white thick discharge.. About 30 mins later (now) it is only light pink.
I'm very worried right now and just need some reassurance that everything is alright, or if I should call my doctor.
Anything helps, thanks 💘
