I am 21 years old, and over the past 3 months I have missed 3 menstrual periods. I have taken a total of 5 pregnancy tests that have all come back negative. I have been on birth control regularly since I was 15, and my periods have never skipped or been irregular. Is there a possibility I could still be pregnant and not know it, or is something else wrong with me??
