am i imagining this ? spotting at 10dpo

lmp was may 23rd. next period projected june 23rd. 5 days away from next period yesterday had some very dull cramping in the center of my lower pelvis area. woke up around 12a this morning and seen this when i wiped. the only other thing i feel apart from very very light cramping is sore nipples. yes there is a possibility that i could be pregnant as i’ve been very active. but i kind of have irregular periods. cramping kind of feels how it would feel during “ovulation” and it’s only in the center of my lower pelvis. any opinions ?
