Ovulation after depo

Ki

I know it’s a long shot and I’ve been in this position once before.

The last time I was on depo I only had one injection and took me a year to get pregnant, periods came back straight away.

This time again only one shot, period took nearly 2 months to come back but it was a normal period

I’m desperate to get pregnant, I’ve been take opk since day after my period finished... yesterday I almost had a positive opk but today they are back to faint lines

Helppppp

Anyone got any stories to help?
