I can totally understand why you'd be wondering with all you've been through lately!

I had an internal after a bout of what turned out to be really really nasty BH's that lasted a full day when I was 32 weeks. Could've sworn it was the start of the real deal. After that OB's checked me and I was still closed.

I had another internal at 37 weeks to check how I was looking for my induction.
It's perfectly fine to ask them to check you if you want to - it's your body you have a right to know what's happening if you want to know
