Hi, please I am worried abou my girlfriend. We had unprotected sex on 2nd Feb and she took postinor2 on 5th then saw her period on 9th(a day earlier), then we had unprotected sex on 20th and she took another postinor2 on 21st.

Since then, she hasn't seen her period and we have taken more than 5 pregnancy tests and it's all negative. We are just confused, please what is wrong with her and what can we do? It might be helpful to know that she had ovarian cyst some months back and she was told to take regulon contraceptive for 3 months which ended on the 31st of Jan. Thanks
