hello and welcome
decrease your worries as stress
and work load are one of the major causes if irregular periods
i think this time when you went to your doctor your pregnancy
test must have been done and since there was no conception, your doctor has prescribed you medicines for withdrawal bleeding.
since you have undergone an abortion
just 3 months back, give yourself some time.
I can understand that you are eager to conceive but right treatment will work only at the right time.
follow your doctor instruction, and tell her that you ARE PLANNING FOR A CHILD.
she will definitely refer you to a good fertility
clinic at the appropriate time..
may god bless you.
