Hello, I have had grade 4 placenta praevia (as bad as it can be) twice, with both DC2 and DC3.
In addition to the grades of PP, there are stable and unstable PP. Most people have stable, but I suffered with unstable. This meant I kept bleeding throughout the pregnancy.
With DC2 I was given no advice at all, I flew at 28 weeks without a fit to fly certificate. Admitted to hospital with bleeding at 33.5 weeks, baby born at 37.5 weeks, weighing 8lb 11oz.
With DC3 I was given loads of instructions what I could and couldn't (mainly couldn't) do, including no sex, no pushing shopping trolleys etc. I had 6 separate admissions (24 weeks, 26 weeks, three times at 31 weeks, finally kept in on 6th admission at 33 weeks) we had a CS booked, but had an emergency one at 36+1.
If you have any queries, please ask away.
