Sadly I suffered my second miscarriage yesterday. The details are unimportant but here's what is...with my first miscarriage I had zero symptoms. None. With this miscarriage I had every symptom in the book leading up to today one day past my DE. My point is no matter what you believe, symptoms or lack there of no do not dictate the health of your pregnancy and analyzing them will only make you nutty. So my advice, enjoy being pregnant and live in the moment.
Happy and healthy 9 to you all. I hope to be in 1st tri again soon.
