TTC NEWBIE IMPLANTATION BLEEDING?!

Ok wonderful ladies! First time ttc here! I want to know if anyone has experienced anything similar at all or if I should just seek some medical advice from the doctor, also just curiousity as well! I stopped taking the pill on the 16th. That was the end of my last pack/period time, then on the 23-26 I had what appeared to be another period yay me right? I started taking OV tests just to see if I was ovulating and literally got no results. But I could have ovulated before I started trying to track i guess it was a close call by the time i got into a store to pick some up! Now....i had a very dark couple times of bleeding on the 19th just when i used the restroom it came dark on Saturday then Sunday the 20th just a little bit and very pink. Too soon to get excited about implantation bleeding?! During the time I thought I was about to ovulate my husband and I were very....frisky;)
