I was supposed to start like...I don't even remember. Somewhere around the end of last month between the 28th and the 30th.

I have a very regular period..

I'm 20 years old sexually active, no protection.

But I've taken 4 tests and they're all negative :(

I'm starting to get bummed out. Because my friend said something like..my period may just need to be jump started or something. Idk. I was hoping real bad I was pregnant cause we're honestly trying . but. 4 negatives :(
