Hi,
Welcome to Health Care Magic,
I am Dr.Naveed Ullah khan,
I have read your question in detail and will try to help you in the best way possible.
There is always a chance to get pregnant in such situations although chances are extremely low in the first and last wewk of ur cycle. Still i would like u to do a urine
pregnancy test at least 2-3 weeks after the unprotectes sexual activity. Urine test does not come positive so soon after the intercourse. As for the bleeding it does occur at the begining of pregnancy but agaon very uncommon this early at pregnancy.
Always use a bareier method during sexual activity as it can prevent unwanted pregnancies amd far more importamt its the only way of protection against STDs like
AIDs syphilis hepatotis
gonorrhea etc. I strongly suggest u let your partner use them everytime u have a sexual acticity.
I hope this answered all your queries, if you have more queries,I will be happy to answer.
Wish you the best of health.
Regards.
Dr.Naveed Ullah Khan.
