Period started on the 16th of September, ovulated on the 29th and had unprotected sex. Today I tested negative 11dpo. AF is supposed to start soon (cycle length varies 26-28 days). Been having on and off vivid dreams most nights for a few days now, lots of nausea (I'm usually a huge snacker and nothing appeals to me anymore), lots of bloating, cleaning my toddlers poopy nappy now makes me want to vomit when it didn't before, light cramps on and off and just started having some lower backaches. Am I out? Anyone had similar and still tested positive?
