Questioning Labor


Alright ladies, I'm 34 full weeks tomorrow and this morning I've felt crazy dizzy to the point I thought I'd faint, not having any Braxton Hicks so far but small cramps. Blood pressure is fine but I am on an iron pill for low blood levels and I took it. I feel hot and back is hurting. Also don't know if this means anything but my dog (He's a chihuahua) has just sat and watched me all morning after getting excited last night randomly? Thoughts would be helpful. Thanks!!
