Hi. I Am Having Some Issues And Would Like To

Hi.
i am having some issues and would like to please have sone advise. I had my period on the 23rd and it lasted for four days. I had unprotected sex on the 31st and started bleeding a week after. I bled only a few drops since the last days and had some brown mucus like discharge without any foul smell. I also had lower abdominal pain for a day. Can you please help?
Thanks
