Birth control question

Hi mama’s! I had an emergency c-section on 3/24/21. I had a healthy baby boy! But my question is I started the mini pill, norethindrone, on 5/9/21 and I was bleeding for that week. I am exclusively breastfeeding also. I haven’t had any bleeding since then and I am 2 weeks into my new pack of pills. I had sex before I started the pill. I haven’t taken a test because I’m so scared of what it might say. Lol. Just because my LO is only 12 weeks old. I know I need to, but just wondering if anyone has had this happen.
