Helppppp TMI

I’ve had really bad headaches for the past week and a half. Then like 3 days ago I noticed I was constipated and I kinda still and but feel like I have to poo every so often then go and it’s diarrhea. Also been super tired during the day then when I go lay drown I can’t sleep. Af due on the 11th. Could these be symptoms? Last time I was pregnant I had horrible headaches and tired. But never the couldn’t sleep or diarrhea. Ended in miscarriage March 2018.
