Is this too long between midwife appointments?

[moominsmummy]

Am 28 weeks with no2 just saw my midwife today and all ok as usual.

My next appointment is in 6 weeks time - is this usual? I'm sure my antenatal appointments were more frequent last time - alot could happen between 28 and 34 weeks?

When does the risk of mmc die down though? Could the reassurance-type appointments not be done up until the risk is over and then back to the normal time frames between appointments for women who have a history of mmc?
