Hi Tash

It's possible you are becoming fertile again. It's not uncommon for women to conceive in the first 6 weeks after giving birth!

My SPD wasn't as severe as yours but it did ease up quickly after birth. I found though that I had troubles about 3 months after, especially in the front and in one side at the back. It could have been postural but with things like lifting the washing basket it was obvious that problem was SPD still. I found pilates helped strengthen the core muscles and my bounce back time was shorter if I did something that hurt me.

Not sure about the hungries but as your body is still healing, perhaps it is to do with that.

My body odour changed post partum too. I tend to get BO too
