Hello. It has been about a week and a half since I have had unprotected sex. I got off of my monthly cycle (Which only ever last for 4 days) on the 30th of July and had unprotexted sex on the 2nd of August. I have been experiencing light pinkish bleeding for about a day and a half. The bleeding is going away and I don t see a big difference in my passing of urine but when I do urinate my uterus area hurts. I have experienced some light cramping in the lower abdominal area as well as the upper thigh near the pelvis. I don t know if I am pregnant or what all of this means, but could it mean that implantation has occurred? Thank you for your help.
