Ah mama, discharge changes during pregnancy talaga, pero since you're asking and feeling unsure, it's best to mention it to your OB sa next check-up, or call them now kung concerned ka talaga, walang mababang tanong dyan! They'll be able to check if everything's normal for your 24 weeks, kaya don't worry about bothering them, yan ang trabaho nila! Sending you all the calm vibes, momsh.
