"hello. i have taken the uk version of this pill levonelle once. like pretty much everyone here, i found myself searching for reassurance that everything was going to be ok. i was desperate for it to work after the condom split for the first time ever in my life and i&#039;m 32. i didn&#039;t really have any side effects and my period, thankfully, arrived 2 days early. there is no point in me telling you not to worry as i know i still did when everyone around me was saying not to. however, what i will say is that you are not alone. thousands of others are going through the same thing and strangely i found that comforting. good luck if you are still waiting for mrs flow. hope you have as good an outcome as i did, if that&#039;s what you want, anyway."
