I have a dull pain in my right testicle but i only notice it when i lay in bed at night to sleep. i started weight training yesterday. hernia?

COULD BE: Could also be a pulled muscle. Need it to be checked if the pain worsens or swelling occurs. Breath out when laboring with weight training to lessen the abdominal pressure.

Maybe: Probably more likely to be a groin strain. If you feel a lump there, more likely to be a hernia. See your doctor for an exam if it persists it gets worse. Keep on training!
