Stress and sad 1st time mom.

Im supposedly to be 7 weeks today but went for scan and doct say its to 5.5 weeks instead. Either the baby stopped growing at 5 weeks or too small to advise. The sad thing im experiencing small amount bleeding (brownish) since last 2 days and there was blood clot seen in the scan 😭 today the blood became more red but still small amount.. Doct say do not put so much hope on this pregnancy but yet do not give up as Nothing is certain now.. Doct will review again 2 weeks time. In the meant time doct gave me duphaston to consume Anyone had any similar experience? Please advise
