So, yesterday I took my OPK and it looked really close to the control line but I wasn't sure if it really was a positive so this morning I took it again and it was close again, but slighly lighter than yesterday. For the heck of it I took it again about 5 hours later and the line was barely there. I didn't drink much of anything inbetween testing and it had been over two hours since I last used the bathroom...probably closer to 3 hours. So I am guessing O day is probably today or it was somewhere in the last 12 hours? What do you all think. We bded Friday night and Sat. morning....I tried to get him to comply with me this morning but he was "too tired"...made me kind of upset because I don't want to miss our chance. If we bd tonight do you think it's too late???
