Im scared..

Im 16, ad sex on september 30th protected. Didnt cum inside me, didnt even pull ou we just stopped and hr went to the bathroom and finished himself off cause i was too tired. Now its october 30th i had to get my period 11 days ago but its still not here. Im usually irregular and everytime i have sex i freak out because my period is always late. My boobs dont hurt i do have a bloat but whenever i pressed down i hear like gas build up and stuff. Please tell me im just paranoid and that i shouldn't worry... thank you. Please dont shame me or scare me :(

Oh i also have heartburn and burping and stuff idk and like creamy discharge that dries sorta yellow
