My period is a day late so far. I’ve been getting mild cramps this whole week and i keep checking for my period and it’s not coming. My last period was from December 15 to December 21nd. I’ve had sex 4 times since then. We didn’t use condoms but my boyfriend pulled out. Im 99% sure no cum got in me because he jerked his dick after he pulled out before he came each and every time. Also we only had sex once those days so no sperm could have been in Pre-cum. Could I be pregnant????
