Oo, super normal yan sa 7 months, mama! Karamihan sa amin na pregnant na-experience yan, kaya mo na yung extra weight, plus ang hormones pulling on your muscles, tapos sometimes dehydrated rin tayo without realizing. A few of us tried increasing water intake, stretching before bed, at making sure we get enough calcium, and napansin namin tumaas talaga yung frequency or naging mas bearable lang. But if it's really severe or happening all the time, it's best to mention it to your doctor just to be safe, kasi pwede ring sign ng something else na need checking, basta peace of mind, alam mo? You'll get through this part na, mama!
