From your description it does sound that you may be having hormonal imbalances that are causing the symptoms that you are facing,
You can take some painkiller like Advil for the present problems, and if the bleeding persists, then Tranexamic Acid tablets may help too.
Resting, warm fomentation on the abdomen and fluids may help,
The abortion should not cause problems after 2 years,
I would like you to consider the hormonal pills, these are only for a few cycles for most women, and they may help normalize your periods,
Take your iron supplements as advised too :)
