Ok, so I had my period on the 25th May, and I had sex with my boyfriend on 15th of June, we used a condom. However roll on 25th of June and I haven't had a period and still haven't had a period and its been 3 weeks, I did a home pregnancy test (clearblue digital) a week after my period was due, and then a week later I did another test, and both came up negative? Do you think I might be pregnant? I'm going to get a blood test on monday but I just want to see what pthers may think?
