What are the chances it could be a girl

We were not trying to get pregnant we were having sex everyday sometimes three times a day what’s the chance of having a girl since I heard to conceive a girl it has to be days before ovulation because the sperm is slower and the heart beat is 158 I had a boy before and I was throwing up all the time with this one I haven’t thrown up at all I was only nauseous and I’ve felt this baby move much dinner I been feeling little flutters and pressure on my tummy like the baby puts pressure and with my boy I felt him move intill late pregnancy I also had another pregnancy after my first I was pregnant again but lost it and with that one I never threw up either only was nauseous I sometimes feel it’s a boy and sometimes I feel it’s a girl
