Hello Lisa, If I was in your shoes and I am late on my periods, I would visit my gynaecologist because he/ she will be in the best position to tell me what's going on and do the necessary tests. People on this site can just give their personal opinions and it might not be true in your case. Having said that there are many reasons for getting periods late, not just pregnancy. Visit your gynaecologist and let them give a proper diagnosis. Hope this helps.
