Body temperature

If God’s willing, tomorrow is my official 4weeks. I had 2 miscarries already. I have to take PT and Thank God it is still BFP for the last 5 days. But I fear when I feel cold, my husband is hot. But I need a blanket on top of comforter. It just scares me. When I had miscarry, I feel cold too. Except I don’t feel much cramps this time. Is headache normal for 4weeks and being cold on and off?

Also, what do you do to ease your anxiety for two months before seeing your OB?
