I am 41 years old and have been taking Quasense b.c. pills for about 3 years now. My period was due on Feb 2nd but I have yet to have it. I am usually very regular with my periods. Being on Quasense, I normally have my period every 3 months like clockwork. I am having all the symptoms of pregnancy including stomach cramps, low back aches, severe fatigue, sore breasts/nipples, gas, constipation, nausea, bloating feeling and even very vivid dreams. I have taken three home pregnancy tests, all of which are negative but I still think I m pregnant. Any words of wisdom for me? I have two kids already although they are now 18 & 19 and I feel exactly as I did with both of them when I was pregnant. How long should I wait before taking another test?
