That's the worse. I'm now 31 weeks and lost my energy around 28 weeks again. Hang in there!
That sounds like how I was from weeks 6-13. For me once I hit my second trimester it was like a switch got turned back on and I no longer needed a nap once a day or more
This is very normal. A lot of women will get at least some energy back in the 2nd trimester. However, some women then lose their energy again in the 3rd.
