rhogam shots

So it's not my first pregnancy where I had to get rhogam, but it's my first pregnancy where I've had multiple shots (2 now). Just didn't know if anyone else has had to have 2 or more during one pregnancy, I'm sure it's ok, but just wanted to see if anyone could make me feel less anxious that I just got my second shot :/. First shot was back in October around 7-8 weeks, and now today at 26 weeks.
