Hi. I am 10 weeks 6 days preg. My hcg is doubling in 48 hours. But for safer side doc suggested me to take hcg 5000 iu injection weekly. 1. Pls confirm till what time I should take hcg injection or should I stop it? 2) baby heartbeat at 9 weeks 6 days is 168 bpm. Is it on higher side? 3) doc has suggested double marker test 10 weeks 5 days. Is it the correct time to go for the same? 4) m taking susten sr 300 mg twice. Is it sufficient dose? 5) m taking bigomet sr 500 mg twice daily as I have pcod. And till what time I should take bigomet and when to stop? 6) also m taking bharglob in every three weeks (immunoglobulin) and enoxaparin 40 mg daily as I had 3 previous miscarriage at 6 weeks.
