Tips for anything specific? I recommend some prenatal yoga if you aren't too sick. It will definitely help you prepare for the 3rd trimester and birth!
Try to remain calm. Everything that happens is normal.Women have been doing this for thousands of years and your body may just need to adjust to changes. Dont panic if someone says you should be at a certain milestone and you are not, just listen to doctor. If he/she says you are fine, you are. You will be fine, you got this.
