"it worked! had brief unprotected sex then used condom for the rest of it, but i took a plan b about 1-2 hours later just to be careful cause of pre cum. most likely after ovulation. started freaking out and reading reviews positive i was pregnant because i overreact like that. i had slight nausea and diarrhea a couple days after but very little side effects. period came right on time. i&#039;m not gonna tell you not to worry because i did that no matter how many reviews i read, but use this feeling to make sure you don&#039;t make this mistake again! good luck"
