hj1981, I know it can be extremely confusing trying to figure all the signs of ovulation. Maybe you could try using the ovulation predictor kits (OPK), they are available at chemists etc. depending on how long your normal cycle is, ie 28days, will depend on when you may ovulate. If you have a 30day cycle, you may not ovulate until day 16. If you can't get to a computer often, i would recommend reading "Taking charge of your fertility" by Toni Weschler. I knew a bit about my body, but this certainly helped me a lot. Hoping you you get a big fat Positive (BFP) soon.
Hope this helps abit.
