9 dpo I think I'm out

Had a faint positive but everything since has been neg :( periods not due for a couple of days I think my body's playing tricks on me :( have sore boobs fussy with food headache every morning, my partner said he wants to wait a while if I'm not pregnant this time as I had a mc and then with that positive what's now neg he's stressed :( I could cry and cry but I've got to stay strong ... This mornings tests tweaks welcome but I can't see anything and the positive from the other day ... It must of been a false positive x
