Help! I dont know what to think!!

Ky

I stopped BC last week on the 10th and BD with my husband the following two evenings. On that saturday (13th) I started withdrawal bleeding. That lasted 4 days. Now since then ive been taking OPKS. 2 days ago and yesterday..ive had light pink spotting. Today no spotting but egg white discharge. Could that have been implantation bleeding? My husband just now made me think of it....
