Noticeable horomone shift symptoms (39 weeks)

S.A.

Anyone noticing weird bodily changes associated with hormone changes in these last few weeks? Last week I had a migraine, which I didn’t have many during pregnancy but frequently would get before my period. This is a TMI one but my armpits don’t ever smell except before my period sometimes. Didn’t smell the whole pregnancy. But they’ve been odorous the last few days. I’m convinced these are pre-labor hormone changes!
