me and my boyfriend had protected sex on july 5 and he didnt even finish in me, in fact he didnt cum at all. but i cant stop thinking that i might be pregnant, ive been stressing out about this whole situation for two whole weeks now. i took a clearblue digital test on friday and it was negative, but  a few minutes ago when i wiped i noticed a little blood. immediately my brain thought of implantation bleeding and now i cant stop panicking. my period is supposed to come sometime this week but i cant stop stressing. someone please help me and tell me im not pregnant
