Regards pregnancy problem. Of baby.

I have got pregnant on Oct 2018, My last lmp is 15.09.2018. I have test with pregnancy kit on 22.10.2018. Due to heavy pain, I have visited to doctor chamber. He prescribed me to take duvadilan 10 mg, Susten 200mg, Folvite 5mg. That day Doctor done TVS. Doctor told there is no sac. He guessed this is tubal. This is abnormal pregnancy. This isn't healthy. My hcg level was 1176 on 24th oct 2018 and On 26th Oct 2018, this is dropped to 717. But doctor prescribed me to take those medicine and to take complete bed rest. Doctor told me wait for some days. If period start then you will try again from next month. If not then do beta hcg and report him on 8.11.2018. We are waiting those days and I Don't have started any period. On 7th Nov 2018, My beta hcg level is 3630 and reported to doctor on 8th nov 2018. Doctor done tvs. Then seeing - there is a tiny gestation sac. So that this is trying to be increased as normal gestation sac and no growth of baby.
