Do you have the symptoms all the time or at a certain time of month? I know I started having PMS when I was about 30, had never had it before. Another possibility might be the pill you're on. Even though your periods are regular and normal, it still could be causing a slight hormonal imbalance, either heavy on estrogen or progesterone.
Don't feel like I' ve been a huge help but I did want to give you a reply and also to welcome you to these boards. There is a wealth of information here as well as the whole Power Surge site. So, if you ARE beginning the journey, you've come to the right place for knowledge and support!
I agree with Joyous. Could be the pills...........could be PMS.........could even be perimenopause at 30- it is possible. You could also just be going through a temporary hormone fluctuation, and symptoms will go away.
I started my period a week before my 16th BD and I noticed peri symptoms at around 37 (am 44 now).
What might be helpful is keeping a journal. I have a calendar at work on my desk, and I jot down symptoms as I have them on a daily basis. You might be able to find some pattern (premenstrual, at the beginning of your pill cycle....etc.....)
Also.......is personal life okay?? Relationship going well??? Sometimes things we go through emotionally can manifest itself in some physical way.
Try not to "think" too much. Don't be so busy paying attention to every symptom you MAY have, that this time in your life passes without fun or joy.
If it is perimenopause, as joyous said, it can go on awhile. Listen to your body, educate yourself, but try not to forget that this is your life, and you need to LIVE it!
Good Luck.............we'll be here if you need us!
