Heyy:)!!!

I don't know if someone would read this Lol. But I'm just writing because I can't sleep... I have been thinking about pregnancy for a month and I don't know what to do. I took plan b and it was 2 days after my period. Then the typical story... Had a brown discharge 7 days after plan b, that discharge was on may 27. My period was due for june 14 but it didn't come! :) i had pregnancy test june 17 and was negative BUT I'M GOING CRAZY HERE!!! Actually I have wrote a lot about this but right now I don't know what to do to get that pregnancy thing out of my mind. Hopefully i will get some sleep tonight:)
