I'm 25+4 with 3rd baby, but 12 years since last pregnancy.
For the past few hours I've been getting a pain in my lower left hand side - reminds me of ovulation pain. It's been coming and going every few minutes and lasts a few seconds each time. It's there no matter what position I'm in or whether I'm walking about or sitting/laying down. Baby is still active and feeling movements more on the right side and further up.
