How far along can I be if I’m seeing faint lines?

Hi ladies.

Just yesterday I tested 5 times and I got multiple faint lines. They were visible but not super dark. I will attach a picture.

I called my OBGYN to schedule my first appointment today and upon asking me their basic set of questions, the nurse on the phone calculated Me to be approximately 5 weeks preggo.

However, hubby and I have only gotten busy the weeks I have been ovulating which is the 10-15th of every month.

I got my period last month (April 26-May 1st) which means I would have conceived this month not last month as they are calculating it to be...

Am I missing something? Does anyone have any feedback on this? How far along can I really be if I’m receiving faint lines?

Any input is appreciated
