This afternoon my lovely husband phoned the fertility clinic to make us an appointment. We're scheduled for next Wednesday morning. Maybe this will lead to us getting some answers at long last! There are some additional tests the fertility specialist can run, but they probably won't be doing them next week (it'll be CD19 when we go in).
I feel as though I'm going to ovulate soon... I hope I'm right! It's only CD13, but all the signs indicate ovulation being imminent; I even had EWCM today, which I don't tend to see all that often (I always get watery CM during my fertile time). Fingers crossed, anyway! :)
