Just dont feel right, is it normal?

Hi ladies I was hoping for a bit of advice as this is my first pregnancy I'm inexperienced and need your wisdom! At the moment I'm 13 weeks along and got to see our amazing little baby a couple of days ago and everything looks great thank God. I suffered with severe morning sickness from weeks 5 - 12 and have lost a stone (although not a big deal as I had the weight to lose anyway!) Since the ms has subsided I expected to feel like my normal self again but instead I've started noticing other mild symptoms that I think are normal but all together they are making me feel quite run down and not myself. mainly things like diarrhoea, headaches, mild nausea, a gross taste in my mouth, feeling really exhausted all the time but struggling to fall and stay asleep. All the things have kind of piled together and are making me feel almost as if im coming down with something. I'm dealing with it okay but after 7 weeks of feeling so ill will the ms im just feeling a bit tired and overwhelmed that there are now other issues. I guess my question is have you ladies felt like this during pregnancy? is it normal? is it just the ass end of the first trimester making me feel crap or will i feel like this the whole time? sorry for the massive whinge but theres only so much your OH can take 😂😂😂 thank you in advance ladies xxxxx
