I tried to look a few pages back for this, but got tired after 20 pages! And there's no search for forums grrr!

Anyway, I started using opks this cycle.I think i ovulate on CD16-18 which will be the weekend, but my opk (boots own brand) this afternoon showed up with a line that was about the same colour on the left hand side and lighter on the right, half and half basically. I havent got any ewcm yet, and as i said, i dont think i will ov until later in the week. I haven't got a pic unfortunatly.
I looked on www.peeonastick.com, but if i'm reading it right, it says it can happen, but doesnt give a proper answer.
Anyone had this?

A line like that sounds like a positive to me. I would BD ASAP and keep testing until the line goes again - you might get a few days of lines.
