Yes, bleeding during pregnancy is not normal; spotting can be though. Really sorry that the doctors seem to be unprofessional, causing you to lose your twins. Do you know their gender yet?
How far along are you?
If after first trimester, then you will need a month of full confinement; otherwise you only need to do 2 weeks mini-confinement.
During this period, don't touch cold water; don't blow fan as if you catch cold, you can end up with cold sweat, and can lead to further complications. I developed bacterial folliculitis on my buttocks this mid-June, after my m/c; now still not healed up fully yet, though are much better, to be honest. My Dr hubby said can take at least 6 months to heal completely.
not sure the gender but I got a strong feeling that the twin are boys. after my miscarriage, 6 month later I conceived again but this time only one baby.
