Could be if your periods are normally regular, get a pregnancy test at pharmacy or go to doctors and get them to do it. Have you been using protection and what have you been using ???
Hello! When your period is delayed the first thought is always the chance of pregnancy if you have had unprotected sex but there are also other reasons your period is delayed such as stress, hormonal changes etc. I think you should take a preg test, if its negative maybe wait a week to see if your period comes as you may just be having a longer than normal cycle. If it still hasn't arrived its probably a good idea to see your doctor for a blood test.
if your having unprotected sex then you could be pregnant your late so you can take a pregnancy test its the only way to know for sure if your pregnant
