Ok, I want to find out a few things before i take this test because i have been constantly disappointed over and over again. its october 27th and i ovulated on october 17th which is 11 days ago. i have been having these 'cramps' for 2 days and they only happen at night and they feel like they are only on the left side of my uterus. and now when i sit up my stomach kind of hurts (im also overweight) and i have to lay back because its way to much pressure. it has never done this before. my period is due in four days. could this be implantion cramps. and i also had this little little drop of blood earlier. i dont want to take a pregnancy test to be disappointed again but i think it may be different this month.
