Congrats on the birth of your son!
I also had high pressures postpartum after the birth of my second child. My OB at the time wasn't very good at dealing with my postpartum blood pressure, I had much better luck talking to my GP. If your pressures are still running that high today you could talk to your GP and get a second opinion. Personally I wasn't comfortable walking around with a distolic in the 100s.
We have had some posters who have even seen an internal medicine doc or a cardiologist postpartum because of rough recoveries or lingering high blood pressure. You are still pretty close to delivery though, you might want to try your GP first.
Good luck, please keep us posted as you are able!
