doctors?

Ch

not sure if I should be concerned. this month and last month (ever since I started ttc) my cramps the day of my period starts makes me bed rest. no pain meds can help it. I burst into tears. it only lasts 24 hours. also last month my period was 2 days early then this month it was 4 days early. I don't know if I should make a doctor's Appointment or wait till next month to get looked at. opinions?
