Hello doctors, please my sister is facing a serious unpleasant condition every month during her mensuration, it happens that whenever the time comes for to mensuration as a woman but I won't be so she experience frequent vomiting and ache on the abdomen all that first day till second day before sighting any relief and she doesn't take any medication for for now to avoid side effect or complications during marriage, last time she tried taking paracetamol it caused the to run up to seven days mensuration since then stop using medication during pains and vomiting. 1. Please could it be because she still keeps her virginity at 22? 2. What home remedy or solution to this problem because she suffers a lot on that first day? 3. Can this problem cause or hinder her from conceiving (pregnancy) when she gets married? Thanks in advance doctors, God bless you all for this selfless service for humanity.
