Pliz help me

well the problem goes like this, The last time I slept with my boyfriend was last year on the 25of january and then when I went home I discovered there the was some blood on my pant and then I started my period but I wasnt suppose to start that earlier, and then within 4days I end my period which I was suppose to end after 6days and then after 4 days I then started my period again, So for now I dont know what is happening because my date of my period is that I only start on the 7th of every month, so what supprise me is that I started my period on the 25th of December and then I finished on the 28th of december and then within 4days I stated again and then I finished on the 4th of january, So on the 7th of December I didnt have my period because thats my normal day to start my period.

So if you have any option pliz help mie because I dont know what is happening and I dont know when my next period is.

Dear vieey,
Well your dates are a little confusing but from what I can guess you had sex on Dec. 25 and started your period. A week later you had another period messing your period schedule up that usually starts on the 7th of every month. First lets say I hope you use protection each and every time....now, I am assuming your quite young so messed up dates are very normal. Some woman never have a regular schedule. So don't be alarmed yet. However, this does require you to see a doctor; anytime there is bleeding other than a regular period you must always see your doctor. Keep all the dates of bleeding and give this to the doctor he will need to know this.
Sue...good luck
