I'm the same, I feel shunted off to one side and left to my own devices.
With DS (2009) I had a group session once the pregnancy was confirmed where we got all the leaflets etc., a booking-in at 10 weeks, scan at 12 weeks, and then midwife appointments 4 weekly from 16w to 32w, then fortnightly from 32w to 40w, plus a 20 week scan. I also had additional scans/appointments with a consultant due to regular bleeding.
This time round because it's my "second" pregnancy (it's actually my fourth) I'm left to get on with it. I had a booking at 10 weeks, a scan at 12 weeks, an appointment with the MW at 16 weeks, and my 20 week scan. I don't see the MW again until 28 weeks so from 16-28 weeks I've been on my todd with regard to antenatal care. After 28 weeks I won't see her again until 36 weeks, then 38w, 40w, and 41w (if I go that far).
NICE guidelines state that first pregnancies should have four weekly checks but in subsequent pregnancies no more than seven visits/checks are needed if the pregnancy is low risk. I personally think it's awful and that this should only be the case if the mother is comfortable with it, some women want more contact and others want less. I had a late mmc in my last pregnancy so to me the reassurance of hearing a heartbeat and having BP/urine checked is invaluable because it helps ease my worry that it will all go wrong again. As pointed out in another thread, you are four times more likely to lose a child to stillbirth than you are to cotdeath if you're in a low risk group and many organisations, including SANDS, have called for all women to be monitored more regularly in pregnancy not just high risk groups.
I find sites like MN to be invaluable in terms of support and they're always here, unlike the MW. It's a sad fact that many women have to be "pushy" or "a bother" in order to see a MW or OB doctor and that they have to insist/demand to be seen if the need arises outside of their scheduled visits.
Unfortunately there isn't a lot can be done to change the system. Maybe write to your MP or the Health Secretary?
