[|Human|] Hi I had sex when I was ovulating and used the pull out method. I was supposed to start my period 5 days ago. I took a test the day after I was supposed to start but it was negative. Could I still be pregnant? I also threw up a few days before my start due date but I think it was due to a headache?
[|AI|]  Hi and welcome to ChatDoctorPull out method or also called coitus interrupts method is a crude method, and it has high failure rate. It's usually not recommended by doctors as a method of contraception. The fluid which is secreted by male partner before ejaculation may also contain sperms which can lead to pregnancy. Take a pregnancy test once again and if it is still negative and periods are not happening then please consult a local doctor. If test is positive and you don't wish to continue pregnancy, please consult a good obstetrician to terminate safely. Some safe methods of contraception are condoms, oral contraceptive pills, copper T (if u have one child). I advise you to communicate this your partner and ask him to use condoms. All the best Chat Doctor.
