I am 43 yrs old never get pregnant. I have a bf we been almost 2 yrs now. He is 36 yrs old and have 5 kids already. We don't use any BC coz i never geting pregnant and i am 43 yrs old already. But recently i missed my period for 20 days now.

I am 20 days late of my period, in 15 days late i had spotting and last for 2 days, it was just a tiny tiny drop to my panty and that was it and light red every time i wipe after using the bathroom and i had it for 3 days. Now i feel sometimes carmping of my tummy and lot of gas. It could possible i am pregnant? I took 3 times home test but all negative.
