HELP : am i pregnant

So me & my boyfriend had sex for the second time on the 14th of the month. I am on the pill and have been since the new year however I stupidly forgot to take it in the morning (when i usually do) however i took it when i got home. We didn’t use a condom and he came in me. I finished my period on the 25th and am supposed to get it next week in the week of the 29th - 4th. I haven’t experienced spotting or headaches however I have experienced sickness, no actual sick just the feeling. However I wonder if I am making myself sick over it and i’m not actually pregnant. What do you all think, am I pregnant??
