My question is, when you us an OPK, does it detect LH WHILE you are ovulating?? I have had a +LH test 3 days in a row, but figured since it tells you when you have an LH surge 24-36hrs BEFORE you ovulate, that I would only get a + once or twice. Today is Day 18 for me, I started testing on Day 11 with all negatives till Day 16. Like I said, my period is wonkey!! So I am tyring to figure out if I am ovulating, already did ovulate,have a long LH serge or if this is normal, or what since I have not used an OPK before. I am trying to figure out my cycle and if there is any method to the madness!!
