"i had protected sex and he pulled out with the condom on. paranoid, i took plan b (within the 24 time range) anyway because my period tracker app told me i ovulated the next day. i was stressing majorly. the side effects i had included: extreme mood swings, little cramping, and fatigue. my period came one day late and everything is fine. i don&#039;t think i needed this, but my advice would be to use a condom every time and also try to go on sometime of birth control. you can get this at any pharmacy for around $50. i suggest keeping at least one of these stocked in your shelve at home if any stores are closed and you have a bc mishap or unprotected sex. best of luck!"
