Having lower back pains... mild cramps... tiredness... n period is 2days late

Two days late is too early to have signs of pregnancy for most women.

Wait another week, or two. If you period still doesn't arrive, than try a pregnancy test using first morning urine. If it's negative, wait until your next period is due. If you miss it as well than try another pregnancy test or see a doctor for a more accurate blood test.

I really feel like I should make that response into a sticky, I post it so often. :(
