I ordered some birth control pills online a couple of weeks ago. I just received them in the mail today. I opened the package which contains 21 pills in each small pack. These are supposed to be 0.15 levonorgestrel and 0.03 ethinyloestradiol pills. Most birth control pills have a number on the pill telling the strength but when I checked the pills there was no number. The package says Oral-L. So my question is are these pills fake? I've taken other kinds of birth control pills and they all have a number stamped on them but these pills have nothing.
