Could this be a sign of pregnancy?

Kelsie

So, ever since Sunday I’ve been getting really bad dizzy spells. Some have been so bad where I’ve almost blacked out and even fallen over. Well just this morning I got nauseous after one and stayed that way until after lunch.

I’ve never had anything like this happen and I looked up symptoms and it showed pregnancy....

So my question is - moms, did this happen to you early on in your pregnancy or does this sound like something else?
