Ohh yes!!! Had a day and a half off sick from work last week, was feeling a bit dizzy and had a few hot flushes, also really tired! I'm ok now, still get the odd dizzy/light headed spell...I think it's just my body telling me to slow down, or bubs could be having a bit of a growth spurt?
Have an appointment with my midwife on Thursday so will mention it then. Also, the baby is probably starting to really squish up your insides (my stomach was grumbling last night and it felt like it was right up under my ribcage!) so your lungs may not be getting their full intake of air, Try taking a few big deep breaths to boost up your oxygen a little, it might help?
