Yeah I would take another test at the symptoms you've described are normal at early stages of pregnancy.
My periods last 2-3 days and i mark them on a calander so i had checked my dates against the last 6 months and this months was late by 4 days. i had cramping on and off like a normally would but nothing showed in the slighest, I had sex with my partner with a condom and he noticed a bit of blood afterward but still nothing arrived so we took a pregnancy test. It came back negative and i left it at that, the next (5) day i felt as if my period had come as there was bits of blood when i went to the loo and by the 6th day there was average amount of blood that lasted 1 day and spotted the next. As the feeling was much like my period i didnt think much of it but i am wondering if i took the test too early as i have symptoms i mentioned above.
If you didn't come on and was due around the 7th July I personally would take another test and book an appointment with your GP. What is your period normally like?? Heavy/Light? How long does it last? Compare your answers with how your period/bleeding was this month.If your normally medium/heavy flow and you found it was lighter and lasted less time than normal then it could indicate implantation bleeding=pregnant. But it could be something else, take a test... it can't hurt. Good luck x
