Hi, Welcome to Health care magic forum.
I don't know why people are so concerned about being pregnant. The ovum is released from the 11th day to the 20th day of the period if one have sex during that period, or the actual ovulation day only pregnancy
Some people may have infection, if they have sex during the period. It would have happened to you.It is causing thehead ache, nausea
Take more of green leafy vegetables, pulses, sprouts,and
protein rich foods to have good health.
Wishing for a quick and complete recovery. Thank you.
