Yes this is perfectly normal Hun, I had 24/7 MS the whole way through my Preg & it really got me down too!
To be honest I didn't really enjoy being pregnant at all, I didn't find it pleasant or wonderful, the only thing I enjoyed was her kicking!
It doesn't mean you're a bad person. Not everyone has the same experiences & every pregnancy is different. I battled with guilt too about feeling these things. The fact was I felt so blessed to be having our bub but I got the MS, the SPD and just don't enjoy being pregnant.
MS eases for most ppl around 12 weeks so hang in there!
Talking about how you feel is the best thing you can do & honestly BB was amazing for me, the ladies here are so supportive and helpful & you can always find someone who is or has been feeling the way you are & has experienced the things you are!
Good luck hun, it will get easier
