Hello all! I'm new and my husband and I have been TTC for 6 months. I finally decided to try using wondfu opk this cycle. I started testing cd 9, and now at cd 21 I still haven't seen a clear positive. They've all been clear, but not as dark as the control line. My test this morning was the darkest yet. The past 3 days, I've been having mild, but there cramps and sharp pains on my right side and I'm super tired. I think we timed our bd-ing right, but I was out of town from cd 12-15, so... it was every other day around that. I'm driving myself crazy... obsessing over symptoms...going to try to wait to test until 4/1! Any advice/ideas?!
