I had my first ultrasound yesterday according to the Dr she put me at 13wks but the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> has me at 9wks when the ultrasound tech checked the baby is measuring at 6wks and no heartbeat...now they are telling me that I will probably miscarry...I told the Dr I wanted to wait and have another ultrasound next week because maybe we are all wrong with the dates and after 7wks there should definitely be a heart beat...right? i havent had any pains, cramps or spotting. my heart is so saddened...this baby wasn't planned but always welcomed as all babies are blessings please keep us in your prayers I don't know what to think, feel, or believe...
