Hello, I have my last regular Period on 12 th February-16th February. But I took unwanted 72 on 2nd February and 21st February. On March 2nd I have withdrawal bleeding and it lasts for 5 days. But this month, I didn't get my period. I did 5 times home kit urine pregnancy test, All are negative. On 21st April I did Beta HCG Blood Test. Result showed the amount of HCG less than 0.1 i.e. negative. But today 26th April, I didn't get my period. Is there any chance of pregnancy? I have a active sex life and I am 19 years old.
