I will be going for a vacation next month during the first or second week with my boyfriend and I am planing to have sex. I am too scared to just use condoms as I do not want an unwanted pregnancy I want to know about pills. I live with my family they do not know about my relationship which makes it tougher to have pills. But can I use them just for a month? So that I can be sure and safe. Also though I do not usually drink or smoke but as it?s a vacation I will be smoking and drinking too. Ps: my last period was on 16th jan 2019 I had taken a morning after pill on 6th jan I also use to have PCOS but now it?s stable and have regular periods. I want to know all the tips and instructions so that I can enjoy (drink and smoke) and not worry much about my period.
