Hi. I am 43 years old and my period is 16 days late. My cycle is normally 23 to 24 days with my last period on 28th August 2013 but this only lasted 2-3 days and was fairly light. I had unprotected sex on the 24th and 27th day of my cycle. I have done four pregnancy tests, 2 clearblue digital and 2 first response and all were negative. The last test was done when I was 13 days late. Today I have felt sick a lot and vomitted this morning. This evening I have had some brownish/yellowish discharge and then later light brownish/pink discharge. Over the past couple of weeks I have had cramping on and off and a little spotting. Nothing like this has ever happened to me before and the only time I have missed a period was when I was pregnant with my son. I can't work out whether I am pregnant this time or whether something else is going on like early menopause?? I am waiting for doctor's blood test to come back. She is testing hcg and fsh and oestradiol levels. Dying to know if pregnant or not. Can anyone offer any clues??
