Interesting....I've never thought to use a digital opk...for that matter, I've never even seen one! I usually do get a few days worth of pos opk's, then give up after 2 or 3 days. This month I wanted to do the whole thing to see when it goes down. The brand I've been using is first response opk. I like them because they are super quick! I tried the drug store brand but my god they take forever! I'm also charting....chart is super wierd this month...Normally have a decent ov spike and high temps until af; this month, subpar spike, then coverline, then dip below, then litle rise, then little higher, then little higher, and today, 7dpo dip below coverline again!! Honestly, this has never happened before. My charts are so easy to read usually! My biggest fear is I will become menopausal before we get a chance to concieve...
I'm so sorry for your losses....
