scared to updose to 5mg

hey guys so i've already done 6 weeks of 2.5mg and thought i should updose to 5mg since i don't feel na masyado yung food noise suppression like the first 3 weeks. i already bought my 30mg tirze and it's with me na but i read so much bad experiences online just now. i'm scared, should i still inject 5mg? i pin myself every saturday night and it's saturday today. i have a birthday to attend tomorrow, i don't want to feel sick. please give advice 🙏
