I am now about 5 weeks and 6 days preggo. I wish it was a little more so I would feel more in the clear, but like everything it will just be a matter of time.
I would actually say that starting a few days after conception I became extremely tired all of the time. I thought it was just me not being active enough and I chalked it up to being lazy. Then, I found out I was expecting and it made sense. The exhaustion got worse. For the past week or so I have only been good from about 9:30-12:30ish. Outside of those 3 hours, all I wanted to do was sleeeepppp. It was almost to the point of not being able to function.
Before I got pregnant with Kassidy, I went out every single night to hang out with friends. No, it was doing charity work or volunteering. I was usually doing stuff I should not have been doing. About a week or two before I found out I was pregnant with K, I completely stopped going out. All I did with my free time was sleep. I was just exhausted and nothing sounded better than just laying in bed. That lasted until about 6 weeks or so.
For the past 2 days, I have not been nearly as tired. I could actually function and even though my energy is still low it seems like I have had a 2liter of mountain dew. I feel so much better and I hope this part of pregnancy is over so I might actually be able to accomplish something!!
