Am i 29 weeks pregnant? - please look

I had sex in april with my long distance boyfriend. ever since i’ve had a speculation that i’m pregnant. the last time we had sex the condom came off in my vagina. if i was pregnant i would be 29 weeks.

my symptoms- heartburn, back hurting, always in the bathroom, constipation, nauseous( just starting now), hormones are off, bloating, have gained 12 pounds, and it’s also feels like i can feel a baby kicking.

note that i have taken several pregnancy tests starting in june all the way until now. they all say negative. i also have been getting a heavy flow period for 3 days while usually my periods last at least 5 days. i also haven’t grown a lot in my tummy. this is me laying down.
