Low-Ogestrel-28 - its my 1st pack of the pills and Im in the 4th week but I still dont got my peroid

Be patient, it is likely still going to show up. Most women dont start until the 3rd or 4th inactive pill. Even if you start your period the last day, it is okay. Your body is still adjusting to the hormones so it may not be regular for a few months yet but most women on the Pill dont start bleeding the first day of the inactives (some may but most dont) It can start anywhere in the last week. No matter where it starts, you start your new pack after seven days even if your period just started the last inactive pill day, you still start your new pack the day you should. Dont alter your schedule now no matter what your body does, just keep taking them as they come in the pack. No worries, you will likely start in the next day or two. Relax. As long as you took them properly and used back up protection when it was appropriate then you are fine!
