So ovulation was  from the may13-may18 and I had sex the 13, 16, 17, 18, 21 I ovulated on the 18th and after ovulation I've been having light cramps in my abdomen and light lower back pains and peeing a lot. My appetite increased at night for cravings, but a lil nauseous in the morning. It's been 5 days past my ovulation, can I be pregnant?
