I'm back! Thanks for all the good vibes.
Midwife sent me to a&e, so had full bloods taken and urine and examination. Woman this time (with bleeding with dd I had a man and I'm not good with male gynae people) anyway, she was lovely, very quick, but thorough and end result is they don't know the reason for the bleed, but no sign of further bleeds and cervix tightly closed. Bleeding had stopped but still have aches.
Aching can be caused by ligament movement, and my placenta may be low lying so may be the reason.
I'm just glad it went (so far) the same way as with dd. I was even in the same room! Dh came with me and kept me chatting and was his usual supportive self. He was lovely!
Anyway, been told to rest, so bam goes the ridiculously long work trip and I'm in bed with a brew and a biscuit.
