The brand is One Step :/ might look into getting a doctors opinion. Had problems with my ovaries and uterus during my first pregnancy.

What brand of OPKs are you using? I ovulate every month but have never once gotten a positive on clinical guard. I didn't know when I bought them, but other ladies have also said they suck and aren't very sensitive.

I'm not saying it's impossible to ovulate without ewcm, but if she isn't getting any positives on ovulation tests and not having any ewcm then there's a good chance she's not ovulating. Not impossible, just not a good chance.

I ovulated cd21/30

You can still ovulate and not get EWCM.

If you're not noticing ewcm there's a good chance that you're not ovulating dear. Sorry ?

Also testing opk every 10-12hours during my fertile period and this month i've been testing every 24hrs on non-fertile days just to make sure.

I have pretty short cycles usually 23-25 days.

The last time I noticed ewcm was probably 4-5 months ago but havent tried bbt yet. Thinking about giving that a shot before i stress too much! :)

Do you notice if you have any ewcm? How about taking your bbt? You may want to include those methods with your strips to see if you are ovulating or not. If you really don't think you are you may want to discuss that with your doctor and see about being put on clomid

How long are your cycles? Are you testing every 12 hours or 24? It's possible to miss the surge if you test every 24 hours
