Don’t know what to think / Progesterone problems

Don’t even know where to start. According to dates I’m suppose to be due Oct 27 making me 7 weeks today I’ve been going for blood work for the past two week just checking in numbers first appointment hcg was 4,613 and progesterone was at 12.60 and that was at 5 weeks. And the appointment after that my hcg was at 14,259 and progesterone dropped to 6.78 they called me with results asking to come in for an ultrasound yesterday at 7 weeks. While I was there they confirmed a heartbeat of 116 and only measured 6 weeks they also decided to put me on 200 mg of progesterone orally. I asked about doing suppositories or something stronger since it’s very low all he said was we will do this for this week and come back next week for blood work and we will go from there, we can only do so much. Reading papers they sent me home with about progesterone supplements and all the kinds there are at the bottom it shows oral supplements are the least effective which makes me feel not so great about what they put me on I feel like they are not even trying to save my pregnancy. What should I do?

He asked if I have spotting, bleeding symptoms of anymore kind and I told him with my last two pregnancies symptoms didn’t hit me until 7 weeks in the dot this time I don’t even feel pregnant and I’ve had no bleeding.
