I just had a baby at the end of December, so at the end of January I got my first period and started taking Loestrin 24 Fe (prescribed to me). During the month of February I experienced a little bit of spotting, which they say is normal during the first few months after starting birth control, and got my period when I should have. But starting at the beginning of March, I became extremely irritable and snappy, as if I was having PMS times 1,000. I also experienced very heavy spotting. Nevertheless, 2 weeks after I got off of my last period, I got my period again for no reason, with no change in length or heaviness. Having just got off of that one a few days ago, I have now gotten my period again today, with no change in heaviness. And I am still extremely irritable and snappy. So at the end of this month, I will no longer be taking this product.
