Sorry to hear that Chryss.
This is my second pregnancy but I never experience that. Its always them who make an appointment for me. If a forget my appointment they will always remind me thru phone or letter.
If my midwife is not on duty or on holiday during my appointment there is always another midwife who will check me. During my first pregnancy i have a total of 12 appointments and 3 scans. For the second now its 8 appointments and 3 scans still, one to go. Well, they always put it in the MY NOTES ( your records while u r pregnant). If I cant make it for my next apointment i can always asked them to re sked it for me.
By the way I live in england but choose scotland to have my baby. Meaning i have two sets of midwife and consultans but i have never exp any problems with my bookings and appointments.
Hope you will get that sorted soon. You need to have a scan.
Goodluck.
