Doctor: Hello,Thanks for the query.The symptoms you have mentioned can be seen in early pregnancy, but they are not specif ic for the same.It can also be a part of premenstrual symptoms as the pregnancy tests have been serially negative.Consider consulting a Gynecologist for a beta hCG blood test. This is more specific to rule out pregnancy. If negative, the Doctor will put you on withdrawal bleeding with progesterone supplements.Hope this helped.Regards
