If you're pregnant, you wouldn't have a period at all. It stops during pregnancy because an egg is fertilized.
Sometimes it depends
Perfectly normal. Some get it at 10 and others at 17. All is different.
AnswerLexapro definitely affects the menstrual cycle and can stop periods completely. It's happened to other women, which an internet search will confirm. That this is not listed as a side effect on the package insert is negligence on the part of the pharmaceutical company. Maybe they didn't bother to test the drug on women before putting it on the market; this wouldn't surprise me one bit. I've been off Lexapro for more than a year and my periods have still not returned to normal. It's onlyl a matter of time before the pharma company is sued for causing infertility and induced menopause.
