Hi there, I am 46 yo and ttc. Last lmp ws 4 July 2013. Ovulation ws 17 July 2013. Cramps started 3 days later then stopped when I started bleeding on the 23rd and 24th day of my cycle, I stopped after that. Cramps started again on the 2nd August, and I have had a small break today the 21 August 2013. The bleeding was light, but bright red, pink to begin with, then red, I wore a tampon and thought af is here, then 2 days later it stopped. Thought nothing of it until now. My symptoms have been increased sense of smell, headaches sometimes, pee a lot, moody, and jst cramping a lot, dont know y but jst am. I still haven't had a period and I am normally 35-42 day cycle, but this time around in July a 28 day cycle, ridiculous, I have irregular periods, and am on blood thinners as well, this would b my 2nd pregnancy if I ws, I jst took a hpt, it was negative, wat should I do?
