Ok, I feel a bit of an expert at this as I had placenta praevia with DC2 and 3!
Firstly, check that you can fly. With dc3 I was immediately told I was not fit to fly due to risks with air pressure and the fact that I would be too long away from getting to a hospital if there was a problem.
Having said that, with dc2 no-one told me not to fly and flew to Spain at 26 weeks and back at 28 without any problems.
There are 2 kinds of placenta praevia, stable and unstable, or ok and bleeders. I was the second, both times.
Most people who have low lying placenta find it does move before 32 weeks, but it isn't the end of the world to have a section, but it would be harder for you, being on your own, unable to drive.
With dc3 I was given very restrictive advice, but I had already had complications the first time. I was not allowed to carry shopping, push a shopping trolley, fly, the list went on......
With dc2 I had a big bleed at 33.5 weeks, which then kept on in small quantities preventing release from hospital. Baby born by CS at 37.5 at 8lb 11 oz's so thanking my lucky stars she didn't go to term! No problems and home after 48 hours. But his means I was in hospital for 4 weeks, you may need a childcare back up plan.
With dc3 now 2.5 I was surprised at how differently the same hospital treated it, so were they when I told them about the previous lack of any advice.
I was admitted at 24 weeks, 26 weeks, 31 weeks then three times in a week at 33 weeks at which point I had to stay in until the birth.
After the first admission I was told to start maternity leave - my response was to tell hem they were not living in the real world, next suggestion was 2 weeks at home, not to be left alone at any time (this was seriously the worst part). After 2 hours back at work, I was re-admitted. Then allowed to do part time from home.
The biggest thing is to be aware you may need help. Having said that I know 3 other people who had pp and had no problems whatsoever. I'm happy to hold your hand if you need support.
