hemorrhoids and diarrhea same day?!

I'm 39+5 and got the worst case of hemorrhoids I've ever experienced in my life today. I couldn't sit or walk. They were excruciating, sent my husband to the pharmacy for tucks pads, ointment cream and witch hazel. Been using the pads and oitment which have helped. Now all of a sudden tonight I get diarrhea, which is odd since I just developed the hemorrhoids. What's happening? Should I be anticipating labor next? Thanks
