Well you are worried since you are not menstruating even if you are aborted. This can be due to the hormonal
suppression caused by the depo provera you took some 4 months ago.I also want to know whether you had undergone a D & C after your miscarriage
.Many a times menses resume late after a termination of pregnancy
also.Well ,i would first advise you to do a pelvic ultrasound
,even if HPTs are negative, so that you are extra sure of your normal endometrial cavity, that nothing is inside and the lining is good. If that is normal, then you can go for a withdrawal bleeding with progestrone
containing pills after consulting your doc.If you had done a D & C,after the last miscarriage, then its of value if you don't get a normal withdrawal bleed.
WELL, I THINK THINGS WILL BE FINE. GOOD LUCK
