Is this just pregnancy... πŸ™„

Hi guys! I hope you all had a lovely Christmas and new year?

I am pregnant (21 weeks) and due in May!

I have had thyroid issues throughout the pregnancy but am now off medication.

I am EXHAUSTED! my knees feel like they're about to give way whenever I walk more than 10 steps, I'm tired, irritable and really struggling to complete basic life things - like cooking dinner or filling the fridge πŸ˜‚

Is this normal? Any advice?

Thanks so much in advance!!
