So confused

Hello, me and my significant other have been ttc this past month.. My period is supposed to arrive in two days and I typically always know before I get my period. (Bad craps or just craps in general) I haven't been having any of the typical symptoms I usually get before a period and I feel pregnant.. I get weird cravings (chicken nuggets dipped in a chocolate frosty from Wendy's) I get a cramp here and there but last night my stomach hurt so much.. I felt like I was going to be sick. I tested a few days ago with a pregnancy test and still nothing. I got a blood test done 2 days ago and I came back negative. I honestly feel pregnant though, could I be pregnant possibly? I'm so confused I've also had really bad gass and have had to pee more frequently. Please send your baby dust.. We really want to conceive it would make us so happy.
