This is unusual of me

So since lastnight I've been wanting pickles and peanut butter which I love pickles and I like peanut butter (barely intake any of it though) And all I've been snacking or mixing my food is with peanut butter I ate breakfast at a little Mexican/Salvadorian cafe I ate beens with the peanut butter and a chicken quesadilla with salsa and now what I really want for dinner is a big steak sandwich with sauteed red onions lots of them and pickles with a lot of peanut butter Idk its very unusual and strange to me I don't think Im pregnant plus took two hpt test from dollar tree and they were negative its weird. Has anyone else experienced this and came out pregnant?????
