I need help :( very new to this

I have a 17 month old that I weaned from breastfeeding last month . I have been getting my period since October and we have been trying since with no luck ,.. I am on CD5 . It was very easy for me to get pregnant with my first but I guess since breastfeeding it has messed up my cycle ... I am currently on CD6 today can anyone help me with what this means .. it seems dark for only CD4 and 5 ... did yours look similar ? Any tips would be great !! Thank u 🙏🏼
