almost 6 weeks and I feel like it's a stomach bug

I feel like I do the first day of my period, pretty much every day now. The farther along I go, the more symptoms there are. I have cramping, diarrhea, constipation, gas and nausea. My doctor says all of it is normal and to stay hydrated and take Tylenol for the cramping. Is anyone else going through this? Most of my friends just had morning sickness. I feel like I have a stomach virus. Does this part pass? I feel like I can't leave the bathroom. 😔 How were you feeling at 6 weeks?
