I am 5dpo and this morning when I woke up... I used the restroom to take a tinkle and when I wiped I saw a light-pink tinge on the toilet paper. This has only happened once today... and hasn't happened again since this morning. What could this mean? I did have unprotected sex on 2 of my most fertile/ovulating days. I've had sore boobs, light cramping and very tired during the day but restless at night. HELP!! LOL
