Sorry to hear that Littlelapin. Best wishes to you and dh.
As Raceylacey says I think antenatal care really varies. My antenatal care last time was something like this:
Started off living in South West:
4 weeks: bfp, saw GP, congrats make appt with midwife for 8 weeks
8 weeks: midwife booking in appointment about an hour, bloods taken, family medical history, height, weight and bmi, urine test. Referred to hospital for first scan.
12 weeks: Scan at hospital
16 weeks: midwife appointment, blood pressure, urine test, heard heartbeat on Doppler.
19 weeks: anomaly scan
At 19.5 weeks I moved to London so obviously changed hospitals.
21 weeks ish: booking appointment with new hospital.
Monthly appointments up to 36 weeks to check bp, urine and listen to baby. Alternated between midwife and gp.
Fortnightly appointments from 36 weeks but ds was born at 37 weeks.
HTH!
