Struggling any advise would be great

Hey guys

Am 25 and have been actively trying for about 4-5 months now.

It’s been nearly a year since I stopped the depo prova injection, I got my periods back within about a month and half.

My periods are irregular but are averaging out at 28days. And I am actively trying on my fertile days on my app but no luck

My last ovulation would of been 25-26th of jan and I did the deed.

I am now on cycle day 22 and for the past 2 days I have experienced watery brown discharge that went pink now I am bleeding 7 days early ?

What should o do guys ???
