So, I always had regular periods. I was on the pill for about 1 yr but I didn't like it as it was changing my moods and making me gain a lot of weight. So I stopped it about 5 months ago and all my periods were still regular. And this month my period decided to not show up. I'm 6 days late, and on my second day late I did a pregnancy test and came up negative... my period is still not here. I was sick yesterday morning and my lower back is killing me. Any ideas if I should wait to do another one or to just not bother and wait for the next period?
