I'm 17 DPO and 5 days late. No sign of AF othet than some cramping that's been going on for the last week. I've been tired and couldn't stop sleeping and now having a hard time falling asleep it's like I'm wired all the time the last 3 days but I feel so tried. Notice my sense of smell has increased as well like when I get in the shower I notice our water smelled weird but my husband says it doesn't have a smell at all. Been super hungry, gassy stomach cramps, headaches, and emotional. My husband even commented he thinks I'm pregnant with the horrible mood swings I've been having. I've also being having really werid dreams when I do finally sleep. 3 BFNs idk what to do. I am going to keep testing every 2 days like I have been and if I hit the 2 week mark I'm gonna go see my doc. Any adive ladies?
