Scared for my life

My boyfriend was down here the second week of January and we had unprotected sex (I’m allergic to condoms). Every time that he was going to do his thing he’d pull out. Something told me to look at the app to see my ovulation week and it was that week (high risk). I showed my boyfriend and told him to be careful and he says he knows bc we both aren’t ready for that lifestyle. We had sex every other day of the week when he was here and every time he would pull out and do his do. I know when I feel a man you know inside of my body bc it’s a warm sensation; not saying that it’s happened before but I just know. It’s been three weeks since then and my cycle comes the week of my birthday (this week). I have yet to experience any of my normal symptoms for when I get my cycle. I told my boyfriend and he is 100% with me on whatever decision that I make. He says to wait and see until my first day that I start my cycle but today I woke and thought of nothing but pregnancy and the early symptoms. I don’t want to think nothing of it but is this normal for anyone? Like not experiencing any of their normal symptoms when they get close to their cycle? I really need answers because I can’t take the stress that I’m putting on my mind and body. I need help please can someone answer question or give me tips or something. Please!!!
