Early periods again!!

Hello Ladies

After some advice....

I had a baby in September and sadly passed away.

My periods came back in November, my next period was on CD30, then CD29, then 26.... I’m currently only on CD24 and seen some spotting :-( with such a short cycles you can’t get pregnant am I right?

I’m not so worried why they are short before my last pregnancy I was always sooo regular!
