Missed Period and Not Pregnent

Hi, I’m 23 yrs and my last period was in October 10TH and I have taken several pregnancy test and they all came out negative it has been 4months and still no period. I have had nausea, heartburn, diarrhea, a little weight gain. I get morning sickness here and there. And I am always sleepy; I can sleep all day and night. Can somebody please tell me what is wrong with my body?

Hi!
If urine pregnancy test is negative then go for a blood pregnancy test. A blood HCG estimation test would be more reliable. If this too is negative then other causes of delayed or missed periods will have to be looked at such as ectopics (can give negative urine/HCG tests), stress whether emotional or physical, hypothyroidism, polycystic disease of the ovary, pituitary tumors secreting prolactin, anemia and poor diet, hormonal imbalance, unexplained or sudden weight gain or weight loss. You will need to consult a gynecologist for this. Take care!
