Hi, Welcome to Health care magic forum.
If her periods are regular, there is no possibility of pregnancy
. If she is irregularly irregular it may be pregnancy. You can get it confirmed if she is pregnant after 12th january by doing the home pregnancy test.If she don't want to have pregnancy she can have I pill
. on the next day of the sex.
Take more of green leafy vegetables, pulses, sprouts,and
protein rich foods to have a good health.
Wishing for a quick and complete recovery. Thank you.
