15 weeks pregnant and still very active

So hubby and I have had sex every single day for the past two years. We are now 15 weeks into my pregnancy and we have managed to continue. My concern is: could we cause some type of damage to the baby by being so active??? We have been trying to conceive for over a year and a half and we finally did. I just want to make sure that I don't do something that's putting the baby at risk or harm.
