Sleeplessness at night

I have difficulty sleeping at night. I am currently in Week 8, had previously taken TCM meds which helped before my first gynae visit before 8 weeks but decided to stop it to avoid complications. Tried sleeping on my left side but it gets so hot that I have to eventually turn to my back but I get woken up few times just to either go toilet or cause I feel a slight strain in my lower back. I don’t sleep with the aircon on cause previously not recommended by TCM. Anyone experience the same symptoms this early? I don’t feel tired during the day, but just can’t seem to sleep all the way at night undisturbed.
