Is pregnancy possible despite negative pregnancy test results?
Patient: I have been on the pill for about a year now and have always had a regular period I don't miss the pill and take it at roughly the same time everyday. This past month I missed my period it's been two weeks so I took a test today and it's negative. Could I still be pregnant? Also, this past month my whole routine has been changed I am now up at 5:30 am and have a one year old could lack of sleep cause my period skip? Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  As you took the pills as per the schedule the possibility of pregnancy is less. Sometimes with prolong intake of pills amenorrhea can be seen. And also as you said alterations in daily schedule like dietary changes,  exercise changes,  psychological stress etc, can also affect menstrual cycle by affecting the hormone levels. As your Urine Pregnancy Test gave negative result the possibility of pregnancy is less,  but if you want to confirm better to go for blood test for pregnancy,  that is estimation of Beta HCG levels. If the levels are less than 5mIU/ml pregnancy is almost ruled out.  Hope I have answered your query. Let me know if I can assist you further.
