Spotting on and off since yesterday never got my cycle since i had a miscarriage and i been having unprotected intercourse is this cycle or pregnant ?

Hard to tell: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result if done correctly. One can test about 3 weeks after sex (3 weeks after when conception might have occurred), 1 week after missing a regular period, or 1 week after having a "weird period".
