Im unsure as to whether i am pregnant or ovulating

Patient: Hi, i am on the contraceptive pill trifeme and finished my period 11/12 days ago, i have just realised today that i am experiecing spotting and stomach cramps that feel like hunger/period cramps. i had unprotected sex on the second to last day of my period, however i took the pill that morning (the brown one) which stops your period is there any possibility that i could be pregnant or is the spotting and cramps due to ovulation?

Symptoms: Spotting, cramps
