I ve been vomitting, nausea, abdominal cramps, mood swings, low back pain and i just feel very fatigued. i took a pregnancy test and it was negative. what else can it be?
Apart from vomiting rest all symptoms are normal during period for ladies.  And sometimes due to some hormonal imbalance it may happen that your period cycle is little imbalance.  Do not worry I suggest not to take any anti pregnancy tablets in the future.  Because there are chances of hormonal imbalance with that also.  For vomiting, you can take Anna acid tablets once or twice a day before your major meal.  And have a lot of lemon juice, so it will help against deny Chat Doctor.  I am sure it will stop.  And wait for your next period if the same thing happens you can consult once your gynecologist for the same.  And yes from a nutrient supplement prospective I suggest to start omega 3fatty acid supplement.  It helps a lot to regulate hormonal imbalance or period irregularity as well there are many other benefits are there.  Take care...
