Mama, please see your doctor soon, fever na umabot ng 39.6, lalo na 2 months postpartum, needs checking even kung walang ibang symptoms. Could be maraming things, but you really need proper exam and maybe bloodwork to know for sure. In the meantime, stay hydrated and rest when baby sleeps, ha? Your doctor can also check if it's safe for your breastfeeding. Praying it's nothing serious!
