im nearly 7 weeks pregnant I woke up with a couple of ulcers and didn't think anything from it, anyway I took my kids school and went the shop for milk and on the way back i had like when you look at the sun and you get spots in your vision and felt a bit dizzy so I sat down and I've had around 5 of these episodes today :( the latest being 2 mins ago ... could it be low iron? especially with the ulcers ? I'm taking vitamins and iron daily is it not enough ? or what else could be the reason for dizziness early pregnancy x
