Should I take a test?!?

I recently got the nexplanon removed and had my first period and since then I have been feeling kind of pregnant. I’ve been sick and my breast been feeling tender, and my nipples feel kind of sore, and I’ve been extremely exhausted. I got it removed the 16th of this month and I had a period two days after but I’m not sure if you could pregnant on your period. But I was having unprotected sex on all of these days before and after my period. Could I pregnant?
