Don't worry, your hcg looks very good
my hcg 13dp3dt was only 182, then 16dp3dt was 432. Im almost 32 weeks now.
MS for me started ard week 7 and didnt stop. I'm still having it now, though less severe.
Absolutely no cravings maybe cos of nauseousness haha.
But also no backaches, sore boobs, fatigue, water retention, varicose veins etc.
Having said that, every pregnancy is different, so don't compare and make yourself stress.
IVF moms go through a lot so be kind to yourself, take it easy and think positive thoughts.
Happy mom, happy baby.
All the best!
