I have been testing for ten days and I did a boots ovulation test yesterday, at 2pm it looked a positive the line in the control window was slightly darker on one side of the line, I did another test at tea time and it was negative, do I still continue to have sex or have I already ovulated.

OPKs can be confusing... they work well for some people, but not for everyone. I would continue to have sex... certainly won't hurt! If you think it was a positive, it means ovulation is likely to occur within the next few days. The LH surge that it picks up lets you know your body is getting ready to ovulate, but not that it actually does... only way to know that for sure would be with a blood test.
Sometimes it takes a few cycles to see a pattern in your test results. Fingers crossed!
