Advice maybe? Or tell me relax a little.

Hello all! I am literally JUST pregnant (4w 3days). I've had 3 kids previously 2 living one born at 19 weeks. My youngest is 6 soon so its been a WHILE since I have carried a baby. I feel so anxious with this one as with all previous pregnancies the symptoms were so much more severe from super early on. This one I have a little nausea but literally no vomitting whereas I had HG from the start before. The other thing that is very different is I am cramping way more. Everything else is a walk in the park but these cramps are hell. I know they can be normal but I am so anxious I am tempted to get checked out to make sure everything is ok. Am I being silly? Thanks for reading
