So long story short-we found out dh has a low sperm count this week. We have been TTC almost 11 months. Trying to time sex even more now because we don't want to "waste" his few strong sperm. Please tell me which opk is darker? I usually ovulate on day 17 it's only day 16 today and I think I may have ovulated yesterday as that test looks darker to me. I started a new med so it may have happened early. We had sex two days ago and were saving his new sperm for tomorrow but do you think we should BD today???
