That sounds maybe related to vision changes. I've read that in the first trimester dizzy spells are caused by vascular dilation and to lay on the left side if you start to yawn or hyperventalate to prevent injury incase of fall. But I'm not sure about the second trimester..because the third trimester with dizzy spells could be a symptom of preeclampsia... I'd just mention it to the doc.
Try also increasing your water intake. It should help... also call your doctor cuz I had symptoms like that and ended up with preeclampsia. And don't let them tell you there is nothing you can do about preeclampsia cuz I reversed mine. Good luck!
Hi, how did u reverse preeclampsia?
