Yes. I had this close to the end quite a lot. My BP would drop & I would have pre labour and then it would right itself again. I usually would sit down with a large glass of water and some snacks with my feet up & it would either get better or I would have some BH's for a few hours... but it would settle for me. I had low BP throughout my pregnancy though. In the last few weeks I've had dizzy spells again, and I've been sitting down and drinking a glass of water and eating a lolly.
