I had one spell of this and it was really scarry because i was driving. Thank god i was sitting at a red light and about 2 minutes from home, but it hit me and i was seeing flashes of light almost. I've read it's normal I was probably 6 or 7 weeks when it happend to me. I think it's just the hormonal change and your body dealing with the changes. I would go to the doctor and talk to them if it continues or gets worse. Good luck!

I'm getting that alot lately, but i'm 39 weeks!! I get it because i have high blood pressure at the moment though so if i were you i'd get it checked out, at least you'll have an answer so you'll know either that you don't have to worry, or how to handle it. :) love and all the best x

I was wondering the same thing to. I'm 7 weeks pg and I get dizzy spells. They just started happening. They are not that bad tho. I just need to sit for a moment and it goes away. I'm not actually sure if this is normal but i hope so.

It happened to me around 17 weeks or so and it was b/c my blood pressure shot up really quick. I went in to the dr. for it b/c I literally passed out and they said it was a pretty common thing to happen during pregnancy. If it continues though, get an appt. w/ your dr. asap!

i dont know how common it is but i also had pregnancy induced high blood pressure that developed into preeclampsia and was hospitalised for 12 days before they induced me at 35 weeks gestation. my bp was around 200/108 and had gotten to the point i was on 3 different heart meds and on bed rest plus spilling protein in the urine (the little dip stick thing they make you dip when you go to prenatal appts.) plus hyper reflexia (overactive reflexes) severe weight gain and edema headaches vision changes anxiety trouble catching my breath and racing pulse.

i had a high risk ob for this pregnancy and he said its high bp is common in the later stages of pregnancy and that its normal for the bp to drop in early pregnancy not rise.

however if you are also haveing
Swelling or Edema
Proteinuria (protein in urine)
Sudden Weight Gain
Headache
Nausea or Vomiting
Changes in Vision
Racing pulse, mental confusion, heightened anxiety, trouble catching your breath
Stomach or Right Shoulder Pain
Lower back pain
Hyperreflexia
go see your doc pronto. and keep an eye on your bp yourself at home its a really good idea to get a monitor or just use the ones at the drugstore.

however that being said the fainting can also be due to low blood pressure.

It is common and considered normal.I was getting them often so I did a ton of research.My blood pressure is always fine so its nothing to worry about.
