i sympathise with the dizziness!!
I am 6 wks, with my first i was a bit tired at the start, few dizzy spells in 2nd trimester, acid reflux and high BP at end (no symptoms from that though) so that was heaven really!! i have a daughter she is only 7 months so i have been busy!!
i dont have the pulling in my belly button but i do ache down there! just had the flu last week and thats made me feel rubbish i think! still feel wobbly! its mad!! i hope i dont get vomiting now that will finish me off i think!
