These cramps are so weird

Missed 2 pills during first week of BCP (not consecutive-3 days apart). Now on CD17. Had unprotected sex CD7, CD11, & CD14. I’ve been feeling so “off” the past 3 days. Slight dull cramping, watery CM, no appetite, headaches, nausea, lower back pain, gassy. What’s really throwing me off is the cramping. It’s not like normal ovulation or PMS cramps I’ve experienced. Sometimes I’ll feel small pricks or pokes (twinges?), dull aching, or tightness in my lower abdomen/pelvic area. Could I be pregnant or am I just experiencing ovulation symptoms?
