Clothing conundrum

I’m only 4w3d, but I’m so bloated that my pants are uncomfortable. I’m tempted to buy a cheap pair of maternity pants, so that I don’t have any pressure on my stomach. On the other hand, after 2 losses this year and no successful pregnancies, I almost assume this one won’t go well either, so I don’t want to change much in my life too soon. Uggghhh, can someone just tell me how to find a magic crystal ball that will show me the future? Uncertainty SUCKS.
