B..
My body is so strange in that it's on an unwavering schedule. I have several sisters close in age. Friends as a teen, that I was around more then my own family. Cycle was never wonky. I can be around non pregnant women, pregnant women...doesn't matter. My cycle is the same every month and has been for 15 years. It was the exact same after pregnancy, too. Didn't even have a heavy first month. So strange.
