I took my very first ovulation test last night and got a very quick positive. So now my question is this...my bf is out of town til tmw will it be too late to conceive then? Also my second question is about charting and ovulation. How do you know how long your cycle is when you have an irregular cycle? Also, I just got completely lucky last night...I don't usually know when I am ovulating. Any advice would be so helpful.
