Ay, mama, since ito ay baguhan ka pa lang at may pain, kailangan mo talaga makita ng doctor mo ASAP, don't wait , lalo na kung tumataas or nagiging worse. Three days pa lang yan kaya sobrang maaga pa to judge, pero discomfort na may hapdi like that ay dapat i-check ng healthcare provider mo mismo, hindi lang assumption lang. One of my mum friends nag-insert din ng progesterone, pero siniguro niya na hinulihan ng doctor ang first few days para sigurado na tama ang insertion at walang problem. Call your OB-GYN na para ma-assess nang tama, okay? Better safe than sorry talaga, lalo na with hormonal meds. Praying it's nothing serious, sis!
