Hi mummies! I THINK I'm pregnant? My period is late by 7 days. I've done three pregnancy tests, all positive (2 guardian, 1 clearblue). I'm obese (157cm, 75kg) so I'm hoping it's really a baby and not any other underlying conditions. Anyway! I'm looking to give birth at TMC this time around (previously went to Parkway East for firstborn). Should I book an appointment straight with my gynae of choice or go to a gp for a referral to the gynae of choice?
