Brief Answer: Letrazole can change cycles Detailed Answer: Letrazole is typically taken for five days beginning day three of the menstrual cycle. It helps to induce ovulation. It is usually used for patients that have irregular cycles. I'm not sure of your fertility problems but Letrazole certainly can change your cycle as you describe. Darkness of light flow indicates the blood is flowing slowly enough to begin oxidation (rusting) and doesn't indicate STD. I hope you successfully conceive soon. if you have no bleeding,check for pregnancy before taking Letrazole again as it is contraindicated in pregnancy.

Brief Answer: let me clarify Detailed Answer: I cannot answer to your doctor's thinking as to why this medicine was prescribed to a 22 YO with normal cycles. Also I am not thinking that you are pregnant if you are having cycles, even if they are light,only that the medicine can change your cycle, including making it lighter. It can take a normally fertile couple up to a year to conceive without there being anything wrong.I hope that you conceive soon. Finally, make sure you aren't already pregnant before taking a new cycle of letrasole.It's not supposed to be used if pregnant,
