Someone pls help me

I'm terrified I'm pregnant. My parents are helicopter parents and they won't be supportive at all. My mom can hardly look at me or talk to me because I just told her that I'm not a virgin anymore. He didn't finish in me, I'm on the pill and it's been abt two weeks. I take the combo NORETHINDRON-ETHINYL every night from about 9:30 to midnight and it varies because of my job but I always take it. I've had no symptoms at all except for some tiny muscle spasms on my right side of my stomach and now, today some spotting. I had sex a couple days before and a day after my period and my period was light. Other current worries have me upset but now where near as much as this situation. I also tend to freak myself out and worry to the point where it messes with my digestion and stomach. Am I right to be scared to death about this? I just went and bought pregnancy test because of this.
