Help meee!

Ok, so I've been trying to get pregnant for about 3 weeks now & I am having a bunch of symptoms. I've had pelvic pain, cramps, constantly having to pee, headaches(even when I'm going to sleep) and constant food cravings about 20-30 minutes after I eat. Has anyone got any tips for me? (P.S. - 2 birth control tests popped up negative)
