Hi. I am 48.5 years old. Last period nov 28, 2013. Have had an occasional irregular period in the last year. Did a home test on feb 15, came up negative and 3 more since then came up negative. No pregnancy symptoms, have had some weight gain in abdominal area. Feeling vibrations movement in abdomen though. Tiny amount of blood late last week. Nothing since then. Difficulty sleeping. Under stress lately, started a new job in early dec. did have unprotected intercourse with husband mid december, who has had varococele surgery 10 years ago, now he is age 50. Your thoughts?
