Hi!  I have ALWAYS had periods like clockwork - 29-30 days but this months I spotted on cycle day 27.  I never have early periods and never spot.  I did have unprotected sex with my husband around ovulation - cycle day 13-14 by bbt charting.   The spotting was a small spot of mucus with pink and brown streaks and it happened again later that evening.  I was bleeding heavier the next morning but I noticed it looked pinker than usual and it didnt last the entire day.  I usually have a medium/light flow on the first day that turns into a very heavy flow by that evening or the next morning.  I have noticed brown/pink tissue when wiping yesterday and today and one small tissue clot came out when I urinated yesterday,CD 31.  I have had severe bloating, mild constant cramping, moody, gassy, headaches, shooting pains in breasts, indigestion/heartburn, insomnia and my bbt has stayed around 97.3-97.5 (usually 97.0-97.1) since.  I had BFN on CD 29,30,31, 32. Could I be pregnant?  THANKS!

Hello, and I hope I can help you today. Pregnancy symptoms vary widely between women, and many of the same symptoms (including a temperature jump) occur with PMS as well as pregnancy, and the most common sign of pregnancy is actually a missed period.  Urine pregnancy tests purchased over the counter are just as accurate as a doctor's office, so if you already have had multiple negative tests, you are definitely not pregnant. Your menstrual cycle may be irregular this month for a number of reasons-the most common one being the stress of trying to become (or avoid) pregnancy.  So if you are trying to conceive, I recommend just having regular unprotected intercourse (at least 2-3 days/week) without BBT charting, actually because your body temperature only goes up AFTER you ovulate, so if you wait for your temperature to go up, you can miss your fertile time.  Furthermore, if your cycle is longer than average, your ovulation actually occurs later, more around day 16-17. So I would wait a bit longer and see if you develop a full menstrual flow.  Once you do, the bloating and other symptoms should go away.  If you continue to have irregular cycles, you may want to see a local physician for a hormonal evaluation. I hope I was able to answer your question today and that my advice was helpful. Best regards,
