Hi ladies, I had placenta accreta with my 3rd pg. Well, percreta actually - the one where the placenta grows through the wall of the womb and into something else.
First pg was a cs, second pg was placenta previa (and cs, obv!).
3rd pg, I found out I had a low-lying placenta at the 20 week scan. They didn't say it was anterior, just low.
At 23 weeks I had a haemorrhage and ended up on the antenatal ward.
At 25 weeks I had an ultrasound scan to check for percreta and they said it was quite likely from what they could see. They also said no one was very good at spotting percreta so they just had to work with a good guess and prepare for all eventualities!
A few weeks later I had an MRI and they said they still thought it was percreta. Not through my scar though, but near it.
At 33 weeks I haemorrhaged and had a crash cs. It turned out I did have accreta/percreta/thingumeta but not where they though. The placenta had grown through my cervix.
Ds2 is fine and healthy and I'm fine now too, but I did have a hysterectomy.
The docs are right though - it is very rare. All the while I was in hospital I kept asking questions about stats and how likely this or that was, and they'd say "um, we don't know, it doesn't happen enough". When they did the MRI they said they didn't know how useful it would be for me but "it would be really useful to have the data to help diagnose the next woman".
You're going to get a baby at the end of all this - mine is sat on the sofa trying to work out how to eat a pear without removing his dummy.
