High BP? Low sugar?

This morning everything was fine, until I went to cook breakfast. Suddenly I got dizzy (which isn't new bring pregnant so I shrugged it off) until I stayed dizzy, suddenly got hot and felt like my body was being literally drained all at once. It felt like I was being pulled down, kinda like my body was too heavy for itself.. like a crash. I sat down and messaged my husband and he came back from his parents and cooked everything. But, I am just wondering, had anyone else experienced this? I'm entering my third trimester and already have one baby, with no complications at all. I thought maybe my BP or sugar levels? It lasted a total of about 5 min. I'm fine right now. Is this normal. First time also.
