Exhaustion

I’m 13 weeks today and honestly my body feels so sore like it’s aching 😩 and I have no energy to do anything when does the second trimester energy kick in ?? I’ve got soo much to do and I don’t have it in me 😞

And can having sex harm the baby because I’m actually so scared me and my husband did last night quite rough and I’ve been getting weird feelings in my stomach scared I hurt the baby but Idk if that’s possible?
