Elevit OPK'S?

Anyone had any experience with elevit opk's? How accurate are they?
Have been given some by a friend and today received my first positive at day 27!
Thanks

I used them for the first time this cycle in conjunction with my temp taking though and had a positive night before my temp rise so we went for it the next morning. And hoping we caught it, dont know yet as Im only 6dpo but have fingers crossed this is a sticky one. Last cycle we did it the morning of the temp rise and I fell, even if it ended in a chemical pg, I still was pg just from that one time. They are pretty accurate and if you got a positive yesterday I hope you took advantage of that yesterday and today. Do another one today and see what you get. Goodluck!

Thanks so much for the reply. I did another one today and it was positive as well however not as strong. Don't worry we assumed I was ovulating and took advantage of the fact last night:shhh:
Good luck to you, I hope you get your BFP this cycle let me know how you go!
