Hi,I am an MBBS student. Since i have gained almost 10kgs during this 1.5 yr i have been having irregular periods. My lmp was 19 april. After that i had unprotected sex on 20th june but he withdrew it before ejaculating. I took an ipill on 21st june. I did not have any withdrawal bleeding. I did upt with morning sample twice to check for any pregnancy one on 4th july and one on 12th july ,both were negative. I'm still worried if i could be
pregnant. I haven't had my periods since then. What should i do ?
