miscarriage

Started with no more pregnancy symptoms then heavy bleeding when I peed. Went to A&E @ NUH but cannot see anything and gestational sac measure at 5 weeks plus. Given Duphaston to take. Continued bleeding then went to seek a 2nd opinion @ A&E KKH. Told the same & given the same med. Continued bleeding for 2 weeks and came back to NUH. Gestational sac still measured the same and they sent me to do a thorough check at the fetal care ctr. Confirmed miscarriage because nothing can be seen except debris. I chose to do D&C which is quicker a week later but a day before the surgery, my gestational sac came out naturally (comes with contraction pain).
