I'm 9 weeks + 5 days & I've noticed I've been getting a lot of dizzy spells lately. Sometimes my vision goes black for like 5 seconds & everything kinda sound muted or muffled while it happens. It literally only lasts for a few seconds but it's kinda starting to scare me a little bit. I have an appointment with my OB later this afternoon & I plan on bringing it up to her but just thought I'd ask if you ladies have had any experiences like this?
