Clear discharge before period or early sign of pregnancy?

I’m 11DPO and on 8DPO I had pinching side pain on and off and bad head aches. I’ve been having tingling nipples and back ache every day since 8DPO and today I’ve had clear discharge that I normally don’t get 3 days before my period. Has anyone experienced this before? I’ve thought about testing in the morning but nervous to be let down.

I feel like I might be pregnant but then again I’ve gotten my hopes up to many times so a part of me thinks I’m not.
