I don't know about the bumps - sounds more like a dermatology thing than a hormonal thing. It's hard to say though without knowing more.
As for your period, you need to make an appointment with your doctor. He will give you a pg test to make sure you are not pg, and then he will give you Provera to make you have a period. At the appt. you can ask him about going on some type of birth control - this will regulate your periods for you. Lot of people have gone through, or are going through this. It's not a big deal - your doc will help.
Good luck!
Im 18 years old and have a question about my period. I get my period lasts for 9 days and it will come like every 25-30 days. My period is usually normal for a while and then will go irregular for like a month or two. When it is irregular i will get it like every 2 weeks for awhile and then it will go normal again. Recently i had my period and when it ended i got it again 11 days later. After that cycle ended i got it again (today), it has been 15 days since the last one. I was wondering if this random irregularity is just becuase of stress at that time.
I am 25 years old and have two kids. I have never in my life had a regular period. I think that some of us are just unlucky. I wouldnt worry about it, I have some of the same problems with my periods. Also, sometimes your periods can be irregular do to stress. Im sure its nothing to worry about.
