I m 39 years old, I had my tubes cut & burned in October 1999, last few years been on pain meds, anti depressants, asthma medication including steroids, gained a lot of weight this past year being on prednisone & not being able to exercise. I have always been regular, including all the PMS stuff the week prior, then a heavy flow 5-7 days after, last month I had a few spots but did not require anything more than a pantyliner for 1 day. Now this month no PMS, no signs of my cycle, I have been feeling queasy, light headed, nausea and extra hungry. Can I really be pregnant?
