Hey sis, parang normal side effects yan ng injectable, ang antok at body aches ay common talaga, lalo na first few months pa lang, pero honestly kung tumatagal pa rin or napakalakas ng sakit, better check with your OB para sure na okay lang, kasi bawat katawan different naman ang reaction! A few of us in our mum group, dami ring nakaranas ng similar pag start pa lang, and nag-settle after a while, pero importante talaga na i-monitor mo at i-report sa doctor mo para peace of mind mo. Kaya mo yan, mamsh!
