Higher chance since postpartum ?

So uh , me and my boyfriend had some drinks this past weekend and i felt the same way i did before (nauseated in waves and diarrhea) when i was pregnant with my baby girl. I already said before that i am postpartum 2 months and i did log my past periods and was ovulating and had sex on the highest day which was his birthday. I'm having minor cramps but no bleeding...(i had pinkish/brown discharge for three days on and off after my highly ovulated date (the 13th)and supposedly my period is suppose to start tomorrow , what i wanna know is if it's a higher chance that i am pregnant again than not being pregnant especially with being postpartum.💙
