I'm not pregnant!!! lol

I'm just wondering how many of you opted for wellbeing scans in your pregnancy.
Typically at my local maternity there's only your 12 and 20 week scans.
And each scan costs $150, and you get $90 back with medicare. So, still a $60 scan.

When I get pregnant again, I'd like to do some wellbeing scans. Around 28, 34, and 38 weeks.
Because of my last pregnancy I just want to make sure the baby is OK.
In my last pregnancy DD had severe IGUR, I had Oligohydramnios which is very low amniotic fluid, and placental insuffiency.
I just don't want it to be that the baby has issues and I don't know.
I'm going to get my OB to give me a referral for a scan around 13-14 weeks to go to Melbourne where the Ultrasound equipment is better to check for Gastroschisis. (bowels on the outside). The chances of it happening again are about 2-5%.

Is an OB willing to let me do more scans? My OB is generally fantastic, lol.

So, I guess the question is, after having a troublesome first pregnancy (which may have resulted in an angel being born), did you have more scans in your second?
