Help me! Anyone please

Ok ladies so I know there are alot of you sweet ladies that wanna be pregnant. So please don’t be offended by the fact that I don’t want to be. ESPECIALLY since Monday I’m supposed to be getting a breast reduction the surgery Iv been NEEDING my whole life. So my husband and I had sex sept 3rd and 12am Thursday sept 5th. I took a plan b on the 6th...

It’s now the 13th and my period hasn’t come yet. When the latest it’s come lately is the 10th-15th. Iv been having light cramps like my period cramps but still no period...I’m not fatigued, no nausea, I don’t feel like I did early in my last two pregnancies...so the last few days Iv been taking pregnancy tests due to paranoia about ANYTHING that can get in the way of my surgery. My insurance is up in two months and I won’t be able to get the surgery after the baby bc we won’t have the insurance anymore by then. And it was already difficult enough to get it approved. I have permanent damage to my spine, and sever back pain to where I might have to literally quit my job. Iv tried everything meds, chiro, physical therapy. Nothing works a it’s my BOOBS! So this morning the 13th I caught my pee in a cup and took two tests one FR and one digital blue. I got a super faint pinkish line on the FR and negative digital. I freaked out and took 8 YES 8 more FR the same exact one that gave me a faint line and they were all negative. Mind you I used the same pee to dip all 9 of them in. The line looked more pink on the tips of the line bottom and top than on the middle. So I’m hoping it was an Evap? How could I get one test with a faint line and 8 with none with the SAME CUP OF PEE?? (I would post a pic but Iv tried taking a picture of it and the picture won’t show the line. Iv compared them all even tested a few by dipping some in longer than I should and some the 5 seconds the directions said to. All negative. Please help. I called my doc to get a blood test but they said the results could take up to a week to get back. My surgery is MONDAY. They will be doing a pee test Monday morning before hand and im praying it won’t be positive. I’m not ready for another baby..has Anyone else had problems like this this with a FR test? I’m freakin out and it’s giving me anxiety 😩
