Hi there and welcome! You start counting your cycle days on the first day of your period, so you're CD5. You should get a good basal body thermometer ( if you haven't already ) and start taking your temperature every morning, as soon as you wake up. It helps if the temperature is taken at the same time every morning. You take your temp before you get out of bed. Most of us record our temps on Fertility Friend website:
Ovulation Calendar and Ovulation Chart - Fertility Charting You can make a free account, or you can pay some money and get a VIP membership, which includes extras. Once you get that set up, you will be looking for a shift in temperature. To get a clear picture, you can look at some of our charts, which is in our signatures. You ovulate on the last day of low temps. Where ever the red lines on our charts intersect, that's your ovulation day. I would suggest you take your first cycle to get to know your cycles. You shouldn't worry too much about each individual temps, they will vary during your cycles. The most important thing is that shift when you ovulate, and after you ovulate your temp has to stay up for the next 12 - 14 days until you have your next period or you get your bfp. You can also check your cervical mucous. Not sure if you've done it before, so let us know if you haven't. You are most fertile when your cervical mucous is clear, thin and very stretchy and it kind of looks like an eggwhite. There are few days when CM is like this, and that's when you should get busy. If you browse this website, there is a lot of information about cervical mucous. I hope I made sense here, if not, let us know
