Could Flashbacks, Dizziness And Nausea Be A Sign Of Pregnancy?

Hi

I haven't had a positive test yet - it's too early - but a bunch of the usual symptoms (plus the fact we've been trying) makes me think I'm a couple of weeks pregnant.

However, for the last 2 days, I’ve been experiencing very disturbing sensations of déjà vu, dream-like flashbacks, dizziness and nausea.

Is this just extreme morning sickness? I don’t actually feel like I want to be sick. But the usual advice to snack regularly on small amounts of food seem to be helping.

Other than the unpleasantness of the symptoms, should I be worried? I can’t get to see my doctor until Monday evening at the earliest.

Thanks

Nicola
