Pregnancy after tubal?

Tia

I got my tubes tied after c section number 3 this past November and because of that I just stopped tracking my periods cus I didn't want to stress myself out if my period came late. I told myself I'd wait til I'm a year postpartum but I decided to track it anyway because my cycles seem very regulated and even though I am exclusively breastfeeding my period came back right away and I get one every month and same deal with my last 2. My period never stopped while nursing. So here I am like 6 days late,my ovaries are sore and I just feel so scared. I know I'm more than likely fine but i feel like I'm paranoid now and too scared to take a test. I'm just waiting for that period to show up . Have any of you or someone you know personally got pregnant after getting their tubes tied??
