Hi welcome to health care magic forum. Both of you should know about the mmenstrual cycles and pregnancy before coming to a conclusion that she is pregnant. Periods start with menarchy and end with
menopause. If there is sex only egg and sperm fuse to form
zygote to grow into a baby then periods stop till delivery of the baby. with out sex pregnancy is not possible. Secondary amenorrhoea may be caused by
anaemia, infection
copd etc. which also may cause engorgement of the breast etc.
false pregnancy can cause all the symptoms of pregnancy including false delevary.
If any one have doubt of pregnancy they can get it excuded or confirmed by urine pregnancy test even at home. She has got a defenite infection so i advise her to consult a gynaecologist for diagnosis and treatment.
Besides i advise her some diet recomendations as take more of green leafy vegetables, pulses, sprouts, milk egg, meat, sea foods, fruits, and juices to improve blood, general health, and resistance to combaat such conditions. thank you for calling.
