Hello. My girlfriend and i had sex when she was on the last days of her period and she had to take emergency contraceptive after 2 days. One and half week later she gets her period again which lasts for 1 week.. we again have sex during which the condom breaks, i change it and am sure that i did not come. Its already been 5 weeks since then and she has not get her mense yet. On ultrasound the doctor said the ‘baby sac’ is empty but there is a small kind of clot on the uterus lining. What is it? Is it pregnancy? Please note that my girlfriend suffers from anemia
