Hi, I am 27 years old I had an abortion

Patient: Hi, I am 27 years old. I had an abortion (D&C) 7 months ago. My period started about 6 weeks after the abortion and I’ve had regular periods in the 4 months following the procedure. However last cycle and this month as well, I had extremely scanty period lasting only 2 days and it’s dark in color. Does this point to infertility as a result of the abortion? Please help. Thanks.
