I feel like I’m out already 10 dpo

BBT dropped some today which freaked me out already but then on top of it I’m spotting now. Nothing is reaching my pad. Took a first response it’s negative but I felt like I saw something ( I have a serious case of line eyes). Not really cramping much and if do it’s really light and only on one side for some reason. Idk. Should I just count myself out? Feeling bummed. Sorry for the small rant. TIA.
