Positive OPK?

​I've been trying to conceive since September & had a miscarriage in October. My periods are very irregular, anywhere from 30-50 days. I've been doing OPKS since March & I've never had a positive until now where I think I'm pretty close! I'm currently on CD 23.  I've been seeing a fertility acupuncturist since March & this month he has had me taking a Chinese herb tea (one blend for 1st half of cycle & a different for second half) in addition to Pregnitude supplement twice a day.  Any thoughts on if this is positive or almost? Thanks :-)
