Thanks for choosing health care magic for posting your query.
I have gone through your question in detail.
Your weight gain and pedal oedema may not be associated with your previous abortion
. Sometimes after abortion, females do gain weight due to some harmonal imbalance and that could be the reason why you are having irregular periods
You should get a USG abdomen done to have a look at your ovaries and uterus
to identify if there is any problem. Do continue your good lifestyle.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
