I started VitB complex this cycle and was worried I hadn't got a positive opk and cd19 today! Last cycle was cd16! Finally just got a positive and confirmed with CB. I hardly ever get a faint line, bottom test is from 10am and top test from 2pm! Crazy difference for 4 hours! Anyway this is the most positive opk I have ever got... Hoping the VitB complex has helped this cycle and hopefully a longer than 8 day LP! Good luck everyone 😊
