Now it is highly possible that I am the world's worst paranoid mother to be but..... I keep feeling these 'bubbling' sensations across my bump, I know that the baby moving can feel this way and they're not painful but they do take my breath away because they come up all of a sudden! They also seem quite low down but then that varies too. I'll go for an hour without having any, then I'll get a lot, some quite strong. What is this????? Normal or a cause to ring the midwife (poor woman!) ? Any help on this would be great, this is baby #1 and although I'm looking forward to having a DS or DD I'm finding this whole pregnancy lark a little overwhelming. I'm now 21 weeks PG.
