I have been trying to conceive for three months now , so far nothing happened . I've tested yesterday and also today in the morning but it was negative . I feel that I am pregnant : I feel hungry all the time , smell things , some pains in my breasts and heart . I'm suppose to have my period tomorrow but tonight I've spotted light blood , and it has been more than 6 hours and it didn't get heavier.. I'm confused : am I pregnant , is this the implantation blood or is it my period.. Thank you

I think you need to wait, see if the spotting materializes into your period.
No point in keep testing, it's far to early.Wait until you actually miss one, you could then try a test

Goodluck
