period may be late due to antibiotics, do you start a new pack of birth control if you dont get your period in the 7 days on the sunday you usually would or do you wait till you get your period and start it that sunday?
Hello anonymous and welcome to DC. If you don't want to get pregnant, continue to take it on schedule and DO NOT wait to get your period first. You can also contact your doctor to verify the instructions. I think I am understanding your question. You are not new to the pill and this isn't your first pack, right???
For instance, if you have been on the pill for more than one month, you would continue as instructed and start the next pack on the specified day whether you got your period or not. If you don't follow the instructions to the "T"... you run the risk of an unexpected pregnancy. Antibiotics can interfere with the effectiveness of the pill and your doctor may recommend using a backup method of birth control for the next 7 days on the next bc pack.
If you are still taking antibiotics please clarify with your doctor for how long you need to use a backup method. Better to be safe then get pregnant because of misunderstanding how other meds can interfere with the pills effectiveness.
Be safe, be well and more importantly... be informed. You are the only one who can prevent an unwanted pregnancy, so do talk with your doctor or their nurse.
Yes, you should start your next pack when it is due no matter what your body did or didnt do. Antibiotics reduce the effectiveness of the pill so you should be using condoms as back up the whole time you take antibiotics and for seven days after finishing them. If you dont do this, you at higher risk for unplanned pregnancy. Antibiotics dont normally delay your period, they usually cause breakthrough bleeding BUT if you did have breakthrough bleeding you may not have a period that month (because the uterine lining has already shed during the breakthrough bleed)
