TMI but finally had a solid BM

Since ovulation I had diaherra and when finally getting my positive it went back and forth from that to constipation. Today at 9 weeks + 5 days finally has been a normal one lol and my symptoms of morning sickness has definitely lessened not completely I still vomit in the morning but so far that is all. I still have excessive saliva, heart burn, sore boobs but at times now I’m starting to not feel pregnant. Could it be the placenta starting to take its place ? I hope so cause man I am over the first trimester!!
