Nipple Piercings

I've had them since July and they stopped being sore about late August. There is a possibility I could be pregnant. Now they don't hurt or puss but my nipples are VERY sensitive to touch & laying on my stomach. My breasts feel really heavy also. Could this just be a pregnancy symptom or could my nipples still possibly feel this way from the piercing?
