Is anyone else?

Is anyone else finding it hard to keep up with their body in these early months? Please tell me it isn't just me. Fatigue has hit me like a train I'm permanently exhausted. I got from being roasting to being so cold I'm shivering. My nausea makes me feel like I'm on a boat..Though I've only vomited once as of yet..touch wood.. and my bowel movements are driving me mad.. I can have explosive diahorre one minute and be constipated the next. I'm so happy to be pregnant but this is exhausting 😣
