Should I tell my midwife?

Rose • Fiancée & Mommy

I was just washing the dishes at home and suddenly my head started badly spinning and loads of pressure was in my head and heart.

I had to grab onto the sink to stop myself falling over.

After it passed (about 20 seconds later) I just felt lightly dizzy so went to sit down.

It's the first time it's ever happened. I'm 37 weeks pregnant.
