Postpartum nausea

Mel • Mummy to a gorgeous girl and beautiful boy

So my son is 9 weeks today and I’m formula feeding. Period still hasn’t returned and absolutely no chance of being pregnant as not had sex yet. Last 3 weeks I’ve been feeling nauseous on and off throughout the day, it’s worse when I eat. I spoke to my gp about it yesterday and he said it’s likely hormones that will settle down. Has anyone else experienced this? It’s horrible. I think my dr might be thinking it’s down to my anxiety as I have bad health anxiety however this feels very unusual for me, I’m pretty familiar with my anxiety symptoms.
