Okay. So here's my story.
May 23,2017. I had my period which ended may 28 whererin may 28 is just spotting. On that day, may 28, we had sex. We just used withdrawal method. 😞 then 17 hrs after we had sex, i took an ecp (yutzpe method). 4 pills then 4 more pills after 12 hours. 7 days after i took the pills (june 6) i had withdrawal bleeding which lasted for 3 days.
I would like to know if im already safe??? 😭😭
Last night june 15, i had a brown discharge.
Can anyone tell if im safe from pregnancy now??
