Periods?!

Since coming off my depo injection my period arrived in January. I'm just going to list my cycle days since then;

1st cycle; 45days

2nd cycle; 33days

3rd cycle; 30 days

4th cycle; 27 days

Is this a good sign of them regulating? Before I had the depo my periods were every 4 weeks. I'm dying to have a family of my own 😢
