5w2d - holding pattern

I'm in a hurry up and wait pattern I think. Frustrated and trying to remain optimistic.
First off. I have no symptoms at all. No m/s or enhanced sense of smell etc. And at last test, my hcg is high enough that if its going to happen it should. I know most women would be grateful to have a symptom free pregnancy, but for those of us who are fertility challenged, symptoms are the only ways we can tell we're still pregnant.
Okay, so I have one slight 'advantage'. Because my progesterone levels don't seem to be high enough and we're playing with meds, I get extra blood tests and since they are sucking my blood, I'm asking for more hcg tests at the same time. Mondays hcg was 3804. A little slower rise than between tests 1 and 2 but still more than doubling in 48 hours. Most recent blood draw was this morning. Now I just need to wait (not so patiently) for my Dr to get the results.
Oh, I saw the Dr on Tuesday. Nothing exciting. We chatted, wrote up some more prescriptions and booked the ultrasound. No weight, no bp, no check-up, no nothing else. Just a regular appointment with my Dr. She did say she hoped I was on major sedatives when they were yanking the adhesions from my cervix and cringed when I said that I had nothing at all, and yes it did hurt.
The U/S is not going to be until Nov 15. The 11th would have been the earliest to see the heartbeat. The 15th is the first appointment after that. I hear that many women with fertility issues are scared that they'll see nothing in the u/s. I'm one of them. Terrified even.
Why does having babies come so easy to some and so hard to others? Why can the heroin addict down the street give birth to a drug addicted baby every year and I can't even have one? How can so many teenagers get pregnant the 'only time' they've ever had sex? Why do people who don't want children, those who abuse children, get to have them, no tests, no questions asked, but we have to go through psych evals, invasive tests and home assessments? Certainly not fair when you look at it.
Anyway, sorry to go off on a rant. I'm just trying to pass time until my next results come in.
