Just wondering if I can expect AF to stay away for a long time again. Didn't get it back until DD1 was 14 months last time. And then I only had it once and was pregnant

I don't want to take the pill or anything. I would use condoms if I had to but I don't really like them. DD2 is fully BF so wondering if for now I'm safe to not use any contraception? But don't want AF to surprise me by coming back early!
