okay this may seem like a really dumb question so sorry

if you get a positive on an opk and i mean strong positive ie line as dark or darker than the control line then is it 100% that you are going to ovulate.

just wondering if i am ovulating each month, no real reason to think that i am not apart from ttc for 12mths now, but when i do opks they do come up strong positives. and i am not temping anymore, i hate it, feels like torture to me and i obsess way to much over it.

was just wondering whether i should go to get a bt to see if i am ovulating, dunno just clutching at straws i guess.

thanks
