Thanks u guys its just been a while n this pregnancy is so different from my daughters....
Congrats on the new baby first of all! Next, all totally normal. The random cramps without bleeding is most likely to be stretching and growing. For the fatigue you can try getting more vitamin b. That can help some.
I would sleep 15 hours a day on my days off when I first got pregnant. Lol. The cramping affter sex is normal, unless there is bright red bleeding and the cramps are unbearable. Just wait til you start getting bigger...your back and hips hurt, and all you'll wanna do is sit down!
