Hi, Welcome to Health care magic forum.
You had ligation, and had period, and then had bleeding for a day, You had the period in a month so there will be difference in the periods. you need not worry about these things, after 6 months you will be regular. Up to that time you may have such an irregular periods
due to the changes in the harmones.
Take more of green leafy vegetables, pulses, sprouts,and
protein rich foods to have a good amount of blood and good health.
Wishing for a quick and complete recovery. Thank you.
