My bp is usually very consistent at 120/70. At my 29 week appt it was at 140/60 and I was told that was fine. Then at my appt this morning ( and I didn't notice this till I read my sheet when I got home so couldn't ask) it was 100/70. I know it often goes higher later in preg, but why would mine have gone down? It's obviously still ok or they would have said somehting, I'm just curious really...
