Hindi ko alam ang exact trimester mo, pero kung frequent talaga ang sakit every few minutes, mas better na i-check mo na with your OB para sure lang, kasi minsan normal lang ang ligament pain or Braxton-Hicks, pero minsan may ibang reasons din na kailangan i-monitor. A few of us mums had different experiences, and the doc really helped clarify what was going on, so don't hesitate to give them a call, especially if may other symptoms ka like bleeding or spotting!
