Early pregnancy. Second baby! Have a read

Been feeling like shit since yesterday woke up with sore sides, backache and overall body is aching I'm 5 weeks & 3 days pregnant! I can't seem too get comfortable and it sore when I try and get up feels like I've pulled lots of muscles. The way my body feels is that it's like having a cold or flu and body is just sore but I don't have any cold or flu.

What can this be? Under my breasts top of my stomach does hurt when I press down gentley

I've been up every single night for the past 2 weeks up during the night needing the toilet and I can't sleep once I've woken up

Anyone similar to what I'm experiencing

Does this sound like that ^^^^^^
