Hi all, I'm 18 weeks and so far been feeling pretty good, but this weekend I woke up feeling really low, and quite angry. I've had anxiety and PND in the past and am worried it could be back, but I'm thinking it's probably just hormones. Also, I blacked out on the tube this morning, so I'm wondering if it could be some sort of vitamin deficiency? Has anyone experienced anything similar - I'm guessing mood swings are pretty common? XXX
