Pregnant?

So i normally get an indicator from my body a week before AF and according to how AF comes tomorrow through the 20th but as weird as it sounds my husband's thinks I'm pregnant and i feel like i am. Last month on the 28th we does the baby dance and i started my fertility cycle two days after and down can live in the cervix for 5 days. I do smoke(very little) and i can't now because it makes me nauseous, i feel like my eyes sight has gotten better and the left side of my lower stomach feels really bloated. I tend to hear bubbles in my lower stomach and i have heartburn. My husband thinks I'm pregnant but i think i have a better chance of getting struck by lightning.
