How do you know things are going okay?

My husband and I are currently expecting our first child. I'm at 11w2d. Due to my insurance I won't be getting an u/s until 20 weeks. My husband is in the army and has been gone for this entire pregnancy so far. I had light bleeding and went to the ER at 8w and was able to see the baby's h/b at 171 bpm. However, my husband leaves on Monday for three weeks and will miss the first official OB appt on the 16th of this month. He's so worried that something's wrong. How do you know? I still have all my symptoms: nausea w/vomitting; tender , cramping in my lower abdomen. My symptoms have gotten a bit lighter but I read that it's expected at 11w due to the placenta taking over. I haven't had any bleeding so my OB isn't worried about the cramping. I pee a lot, have difficulty sleeping. I was all fine and dandy until he got worried which now makes me worried. How do you know when things are going okay? Serious answers only please. Thanks in advance!!
