OMG- long day...but I got a u/s out of it!

SO last night I started some major muscle strecthing type cramps and then had some light light spotting this morning- and I freaked. I was so upset b/c I never had bleeding with DS. But I had a m/c in 2000 and had spotting with that one. And plus haveing symptoms some days and not others I'vebeen feeling not pregnant. Luckily after a call in triage at my dr's office the midwife called me back to come in today. She had them do and u/s and I got to see my little sweet baby and a healthy heart beat at 150bpm. I AM SO HAPPY!!! and relieved! I measured 6 wks and 4 days which is 4 days off from the 7 wks 1day by LMP but they said they won't change the due date for 4 days so Dec 19th it is!
