Help ttc confusing results

So there is five days till my period I’m not experiencing cramps just a little gas I’m feeling exhausted an my nose is sensitive but the last two otc pregnancy tests where negative I’m sad cause I’ve been trying for the past two years since I had my twin daughters an it seems I can’t it makes me depressed because I’m mindful of my body but I checked my cervix it still high sometimes it’s soft an sometimes it hard it confusing I don’t want to be a Debby downer but I was hoping this time was it ugh any advice?
