Help, Still no period after pill free days

I haven’t got my period after the pill free days and now I’m on my second pack. I use Diane 35, any advice? I use it according to the instructions and haven’t missed any of the pill. Please help, I’m worried. I mostly get discharge like watery and it’s color yellowish/slight brown.

Ps.sexually active and he cum inside me since I got on pills(after 7 days of taking it). First time of having pills as BC.
