Could I be pregnant?

Trinity

I’m on birth control I was on the green week which is the period week (for those who don’t use birth control) the first of October was the end of my period and my boyfriend came inside me.. the 1,2,3,5,7,12, and the 17 of this month... I don’t want to get pregnant right now and he knows that but idk why he kept doing it... but anyways. The 15 I forgot to take the pill, so the 16 I took two to get caught up. Now I’ve been feeling sick to my stomach, tired all the time it’s like no matter how much sleep i get I cant get enough!!, I’m supposed to be on my period right now. But I spotted for the first day...(it wasn’t even really spotting) usually my period just hits hard and heavy! It’s always heavy even with me taking birth control. But now my bleeding is really light pink or brownish. I don’t have cramps like I usually do. I usually cramp to the point I get sick to my stomach. But now it’s like nothing. (That’s unusual for me even with the pill). Could I be pregnant...? I need help lol
