Hi ladies, I have a bit of a worry. I had my booking scan at 9+3 because the appointment had to be rescheduled because of some hospital thing. My next scan at 20 weeks is 3rd July. I actually don't need to see anyone until then becaue I'm not having the spina bifida and down's tests at 15/16 weeks. (It's totally inconclusive with twins apparently). Because of the high risks with twins and growth rates etc I'm quite worried about not knowing ANYTHING for 10 weeks. One twin has already dropped behind a little in growth and we aren't 100% sure if they are fraternal or identical yet, although very likely fraternal. I considered buying a doppler on e-Bay so I could at least listen to the heartbeats but I read someone elses comments saying there's wasn't strong enough and it was a waste. My midwife is a slightly narky old mare, so I don't feel inspired to ask her to do a heartbeat check, she'll probably tell me I'm worrying too much. Has anyone had twin experience or have any ideas about what a sensible course of action would be?
