Eh, at 14 weeks uterus mmg dah mula membesar so hardness tu boleh normal, especially kalau you massage sikit dia hilang, tapi because it's recurrent on one side and you're worried, better check with your doctor just to be safe lah, babe. A few of my mum friends pun experience something similar in early pregnancy but doctor dorang confirm semua okay after a quick check, so don't stress lah dulu, banyak possibilities je and most are harmless, tapi kena dengar dari medical team you sendiri to be sure!
