Ay, possible talaga yan, pero maraming iba pang reasons din bakit may back pain at cramps, stress, period coming, or kahit posture lang habang nagtatrabaho, kaya better check with your OB para sure na! A few of us mums had the same worry, at honestly ang safest way talaga is to get a pregnancy test or konsultahin agad ang doctor, lalo na kung unusual para sa iyo ang pakiramdam. Fingers crossed for you!
