I won't get in the snark, but I do have this to say: My OB and GP both told me that liners were fine, as long as I changed them as often as I would if I had my period. To me, that's a "fresh" one every two hours. I go through them like crazy, but I haven't had issues at all, and I'm almost on my 22nd week of discharge out of the whole pregnancy. Plusalso, it's been a life saver when I can't make it fast enough to the bathroom. Somehow, my ability to tell I need to pee has vanished.
Yeah, TMI for some. Oh well!
