Is it normal ?

I have been taking Tri-Sprintec since June so almost 3 months . Sometimes I forget to take my pill but the moment I remember I take it . Sometimes it’s 12 hours after .

Am I at risk of getting pregnant?

Two weeks ago my boyfriend and I had sex without using a condom and that weekend before I had been taking my pill some hours late then usual and even that night took it late . Around 3 days after having unprotected sex through this very moment I been feeling dizzy , nauseous, headaches, low appetite so much lower abdomen pain and throbbing normally on the left side but also all over my lower and middle stomach.

Does anyone know if that’s normal because of the pill or hints that I could be pregnant?
