Important question!!!!***

I miss carried 2 weeks ago stopped bleeding last Saturday, (dark red blood and everything) , started intercourse Monday and last night (tmi) I went to bathroom a hour ago and had very very very light pink spotting on toliet paper. Felt my cervix and it's very soft and open like u could stick one finger in it (I didn't of course , don't want infection) could I have ovulated already and had implantation ? I'm so confused help :/
