Hey Maz you arent crazy mate. I get the same feeling about mid cycle each month. I was thinking i was going crazy. I never wake up at nite to pee and hungry all the time and eating weird things and sleepy and feeling very heavy down there and AF pains. Everything pointed to being pregnant. I even did a test and it came back positive twice and neg about 5. It says on the packet not to read it after 10mins cause a false pos will show up cause the chemical in the test keeps working. Good luck mate i really hope AF doesnt come and you are.
