I am using Trinessa Birth Control for bad cramping and heavy periods. This is my first cycle of it and I have still not started my period. I only have 3 more days of the inactive pill. I know I am not pregnant because I am not sexually active. I've heard it is normal and I have also heard that I should contact my doctor. Has anybody else had a similar experience?

Yes, it is common to miss your period or have irregular bleeding/cycle for up to 3 months after you start a birth control pill. If you are not sexually active ... that takes the worry out, ... so basically you just have to wait for the hormones to regulate.

It is very common for a woman to miss, be late, spot, or even have a full month long period. It will take your body garantueed that first month and part of the next to get used to the "new" hormones entering your body. If you ever get an IUD (mirena or similiar things) they will tell you its normal to bleed for 3 to 4 months, as long as your not clotting. Your body will go through some weird changes EVERYWHERE at first because of the hormones in the birth control.
