I know my care was not typical but I'll let you know what I did anyway in case it helps someone else (or you, of course!). Really, it's ultimately up to you - hospital or home - so please just consider all your options then discuss with your provider your wishes, kwim? I had my first visit at 14 weeks with my hb midwfie that I'd used in the past. I suspected/hoped for twins at that point - I was measuring about 18 weeks by then & the mw felt the baby kick from the outside (I had been feeling movement since 9 weeks). I chose to keep my care super low-tech (no doppler (except a few times during labor on baby B after baby A was born), just fetoscope, no bloodwork of any kind, did NOT want an u/s at all but got scared into it at 26 weeks which is when we confirmed the presence of twins, no ve's at all except a couple during labor after baby A was born). I basically kept the typical singleton OB pre-natal visit schedule (every 4 weeks until the 32-34 weeks I think, then every 2, then every one starting at 36 weeks), I just didn't do all the labs & stuff. She measured my fundal height, took my bp, I checked my urine, and I weighed myself. I think, from what you've posted in another thread about your situation, you'd be safe to bypass any additional u/s's at this point since yours appear to have separate sacs/placentas & you know you ovulated twice. I was also very sure mine were DZ since I took clomid, so I wasn't very concerned about possible TTTS (and at my 26 week u/s the tech said they had separate everything).
