I don't blame you for just being happy that there was treatment! I was, too
Shame your doctors didn't provide you with more information though.
Dysplasia is dealt with differently depending on age & the severity of your case. If you were CIN I than you were probably treated with LEEP (Loop ElectroSurgical Excision Procedure), but I'm just guessing here. No matter the treatment, the watery discharge is normal for up to 6 weeks, and since you've already recovered from that, it sounds like you are healing well
Cause for concern would be heavy bleeding (more than one pad in an hour), having severe lower belly pain, or a fever. Course if you have concerns, don't hesitate to see your doctor!
Best of luck
