Pls help, sorry for the rant in advance

Hello, i am around 16dpo and awaiting a pregnancy blood report(hopefully positive), didnt want to do hpt. been ttc #1 since 4yrs with pcos. So today i masturbated and orgasmed multiple times and then i had cramping in the lower abdomen and saw brownish red fluid with mucous? I have been having creamy cervical fluid last 2 weeks and also i have been having intermittent cramping in the lower abdomen since ovulation, cramping has been coming and going . So is this brownish red mucus along with cramping normal in early pregnancy? Or did my orgasm brought an early miscarriage😭😭😭, i have heard that sex doesnt effect miscarriage but one of my cousin had a spotting during early pregnancy and her gynac told her to avoid sex, and i am scared out of my wits thinking about possible miscarriage due to my stupidity, 4 yrs ttc #1 has been tough and finally when i became hopeful again this happens😭 , should i avoid masturbation or sex during pregnancy??
