usually i get my period right on schedule sometimes it may be a day or two off but for the most part it's normal. I didnt get my period at all in may and i was scared i took like 10 pregnancy test and all came up negative. after a few weeks of it still not changing i decided if i didnt get my period by the end of the week i was going to the dr. so i got my period the end of june on the 19th which was the date i was supposed to get it in june. howwever i missed may's period. i thought everything was okay and now i'm in july and my period is now 10 day's late and now i'm scared my period is never this unnormal.. if i were pregnant it wouldnt be a bad thing i'm 27 but it makes me nervous to not know whats going on with my body. should i go to the doctor?
