Answer
If you have any doubts as to whether you are or are not pregnant, take two blood tests for pregnancy (Beta HCG) 48 hours apart. If there is a doubling of the results in 48 hours it indicates a viable pregnancy. If there is a halving of the results in 48 hours it indicates a miscarriage. if both results are less than  5 it means you were never pregnant, in spite of the symptoms you are having. Keep a careful record of your bleeding. If you are not pregnant you may have some hormonal imbalance and may benefit from birth control pills to regulate your cycle. Discuss it with your doctor when you go in September.
