I went in on Thursday for my first appoinyment . Thought I was seven weeks they said I was five weeks 2 days which looking at my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> is possible because we spent like the week after my "ovulation" in bed lol.... so the ultra sound tech said it was too small too see the baby but that everything looked good. However when the doctor asked what the heartbeat was I said I don't know because the ultra sound tech never said anything... I'm freaking out that something is wrong and the tech just didn't want to tell me
