I went to the doctors today and with that info given I asked if 3 more weeks really seems realistic for what's guessed to be a 7 1/2 lb baby, and he said he believes so. But 70% effaced.. Isn't that a lot?! What do you ladies think will she really be waiting until August 5 to make her arrival? 👶🏼💕
Update: Its been just a few hours since my doctors appointment and I'm having a brownish reddish discharge. Could this be the bloody show?
