Sick or having another missed miscarriage

At 3 weeks I started having tender breast. Fast forward to 5 weeks and one morning the soreness went away and I went from being very constipated to having lose stool (so sorry for the tmi). I thought I was having another missed miscarriage but now idk. I've been having severe nausea for a week now. So my question is could I be sick or does this sound normal?

I'd like to add that I'm on progesterone suppositories so idk if that's why I could be feeling so badly.
