I haven't been tracking ovulation at all this month however last week I used online ovulation calculators to estimate when it would happen and it came back Tuesday / Wednesday. I done a test yesterday a Sainsbury's brand and it came back with a light pink line, I done the other one in the box and same thing. I wasn't convinced so I went and got early tests and I got another faint line. My last period was on the 9th August, has anyone conceived so early?
