Go see your doctor asap. It could be nothing, it could be something. Faiting (unless you have some pre-existing medical condition that causes it)is not normal durring pregnancy. If you can't get in to see your doctor then i would suggest the emergency room. Just to be on the safe side.
Ive passed out a couple of times with this pregnancy, mainly in the first trimester. First time was on my honey moon, and I attributed it to lack of sleep, exhaustion, and having not eaten yet that day. Second time was under similiar circumstances. As long as I take care of myself (which I dont always do well) it doesnt happen. Unfortunately, with work and housework, and a small child, I dont always get what I need in terms of sleep or rest.
I passed out many times when preg. with my son. I would go straight to a doc and make sure it has nothing to do with your heart. Not to scare you but they will give you an EKG to be safe. I found that my reason for this was getting overheated..mostly in an indoor place..and not eating good foods. I had to keep my water bottle close by and some fruit or crackers of some sort. This did keep the fainting at bay. Another thing I had to start doing is not going to the mall when it could be crowded. All the people and the lack of air circulation made me pass out constantly. Checking with your doc would be a good idea.
Smile, life doesn't last that long.
Actually Faintness and dizziness is fairly common in pregnancy.
In the first trimester, dizziness may be related to a blood supply that is inadequate to fill the rapidly expanding circulatory system, in the 2nd trimester it may be caused by the expanding uterus on blood vessels, the presure of it may cause it. Dizziness can occur anytime you rise from a sitting or prone position.
Also, low blood sugar can cause it, I know you didn't skip meals, but just in case you feel this again, carry something with protien and sugar in it, or raisens, some fruit, or crackers.
If your in a store, like purbaby said, it might be an overheated store, especially if you are over dressed, get some fresh air, by going out sider or opeining a window, or just do the head between the legs thing.
Tell your doctor about any dizziness/faintness you may have when you see them next. But since you actually fainted, yes you should report that promptly, it could be anemia or other illness that needs to be checked. Good luck!
try taking someracers along with you from now on & smewater. I read up on that & its caused by not eating for long periods of time. wen you're pregnant the baby takes the most of the food, & nuetrians along with it. You still might want to visit your doctor or call him.
