I hate asking all my questions on here but I don't wanna sound pitiful when I call the doctors. I'm having regular contractions just like I was last week when they said I was in early labor, but now I have difficulty breathing through them. I'm not saying the pain is taking my breath away but the actual contraction is like smashing my lungs and i almost can hardly breathe through them but I'm fine after they hit. I'm also really dizzy. There's so much pressure down there so I know it's not baby up in my ribs plus I've never been like this even with her in my ribs. Do you think I should call the doctor or is it nothing to worry about ?? My body just feels so weird
