So, my hubby and I are not TRYING to conceive. Two days ago I had some very light pink discharge: typically it wouldn't worry me, but I just started my third active week of BC. So, this shouldn't be happening. Yesterday I didn't have any, and just now it's back. I'm so confused. My BC has always been like clock-work? Is this normal?
I posted in more than one group because I wasn't sure where I'd get more answers.
