Will I get my period on Blisovi Fe?

Blisovi Fe is a hormonal contraceptive that has active pills containing norethindrone acetate (progestin) and ethinyl estradiol (estrogen), and inactive pills that contain ferrous fumarate (iron supplement). It is used to help prevent ovulation so that you do not become pregnant. While Blisovi Fe helps prevent pregnancy, it will not stop you from getting your period. After finishing the active pills in your pill pack, you should start your period within a few days. This isn't actually a menstrual period, which happens normally with your menstrual cycle. Instead, you will have a withdrawal bleed that may look like a period but is actually caused by a decrease in hormone levels during the time you are taking the placebo pills containing iron.

Blisovi Fe FAQs

How does Blisovi Fe work?

Blisovi Fe is a form of birth control pill that contains synthetic versions of the hormones progesterone and estrogen. It changes levels of these hormones to prevent ovulation and help you not become pregnant. In addition to stopping ovulation, Blisovi Fe causes you to produce more mucus in your cervix, which makes it difficult for sperm to get into the womb (uterus). It also keeps the lining of your uterine wall thin all month long so that any egg that is released can’t attach itself to your uterus.

What are the benefits of taking Blisovi Fe?

The main benefit of Blisovi Fe is to prevent pregnancy. It can also help regulate your menstrual periods, decrease premenstrual syndrome (PMS) symptoms, improve acne, and reduce the risk of ovarian cysts. Blisovi Fe will not protect you against HIV/AIDs or other sexually transmitted diseases.

How do you take Blisovi Fe?

Blisovi Fe is an oral tablet that you take once a day. You can take it with or without food. You should take Blisovi Fe at the same time each day until your pill pack is empty. Set reminders to help you remember to take your pills every day. Missing pills increases your chances of pregnancy. Don’t skip pills even if you’re bleeding or spotting between your monthly periods or if you feel nauseous.

When you finish a pack of Blisovi Fe or switch brands of birth control pills, start your next pack on the next day after your last inactive pill. Do not wait any days before starting a new pack.

It is not uncommon for you to miss a period while on Blisovi Fe. However, if you miss a period and have not taken Blisovi Fe according to the directions, miss 2 periods in a row, or feel like you may be pregnant, contact your doctor.
