Can I be pregnant when I used a condom b.C and no c*m? Last month I took pills 2wks after period and I'm 2wks into bc and spotting could it be my period?

Yes, small chance.. Besides abstinence, no other birth control method is 100%. The chance is small, but you can get pregnant while on the pills, iud, depo injections etc... It is easier to get pregnant at you age compare to, say, 40. It is difficult to tell if you are spotting from period or could be implantation bleeding, but more likely spotting from period. Do a hpt. Consult doc. Good luck.
