Recommendations for best pregnancy tests for early detection?

I feel like I can burst. My husband came home from deployment early September and I swear we were careful as he came home right as I was ovulating.

But I feel I must be pregnant because my ASSHOLE CAT IS BEING NICE TO MY HUSBAND. This cat has hated my husband for YEARS and the last time he was nice to him, I was pregnant. Now the cat will lay on my lap and cuddle, while my husband sits next to me. Yesterday, the cat even let my husband pet him. The last time my husband tried to pet the cat, the cat let out an ungodly growl and tried to attack him.

My husband is convinced the cat has just warmed up to him. But I highly doubt it, because yesterday I had something like brown implantation bleeding. Usually if I spot like that, I get my period within a few hours but nothing, and my period isn’t scheduled to come until Sat.

And idk. I’m just so excited. I miscarried last time, but the cat knew early back then too. Before, I had been told I wouldn’t be able to have children so knowing now for a year, even though I had miscarried the first pregnancy, that I CAN have children, it’s totally changed my mindset and I don’t know how to explain it, but I am just so excited to start a family.

Editing to add, I love this cat. This cat loves me. He’s basically been a baby to me. But he’s never liked my husband. We even consulted a cat behaviorist at a local university to see if relationship between husband-cat could be fixed and she tried everything. We were going to go for a second opinion next month, because first cat behaviorist said that maybe only an anti anxiety med may help at this point. Our house is ‘catified’ with cat only rooms so our ginger tabby never needs to see my husband unless he wants to, but when orange floof comes out, it’s usually to seek out my husband and harass him. The fact that he is coming out of his cat sanctuary areas to seek me out and sit on my lap and make biscuits, while my husband sits next to me and even lets my husband pet him now is SUCH A BIG 180. Orange tabby fluff and his white fluff brother will always come first and I told my husband, if I had to choose between the cats and him, the cats come first. They came with me into the marriage and they will come out with me from the marriage. If I’m NOT PREGNANT, then my orange tabby finally warming up to my husband is a dream come true. If I AM PREGNANT, neither cat will ever go anywhere and I am just super excited to see our family grow.

Double Edit!!! Peed on a First Response stick and BFP!!! I ovulated 9/15 and am 12 DPO. Amazing because it’s basically a repeat of my last pregnancy down to the exact due date. Booked for a confirmation with gyno next week. Haven’t told husband just yet, but I am over the moon and am enjoying having my orange floof cat affectionately following me around and chirping at me, when normally he’s too timid to do so with my husband at home. The only thing I can think of is precome and frottage with how this happened - last time, I was on the pill but I went off for my husband’s deployment and when he returned, went back on and we were going to use condoms during the 7 day window.
