"Electric" feeling in body a pregnancy symptom?

Kacy

Hey Ladies! I'm almost 5wks pregnant and very excited about it! However my only symptoms so far seem to be trouble sleeping and this ancy, electric feeling in my body that feels very much like anxiety...but more physical then mental. It's uncomfortable, almost like having too much coffee (but I'm not drinking any caffeine) and I'm also worrying that this physical anxiety, jitteriness could be harmful for baby. Anyone experienced this?!
