Thanks for the query to H.C.M. Forum.
Let me explain few things regarding your problems.
One and most important thing is that you are not pregnant at all as after all home pregnancy
tests are negative, so please don't take any tension.
Now Asherman's syndrome , you need not to worry even after your D & C.
Now main question is irregular bleeding and scanty periods.
For this you just have to consult a laboratory and get in blood examination for ESTROGEN
, F S H / L H ratio ( hormones), Androgen/ testosterone level
If all these tests values are normal and within limits need not to worry and live a normal life , if reports are abnormal then upload these reports over this side and we will discuss accordingly.
Hope you will find this information good for you.
