<human>: Could you distill the essence of the text into 1-3 sentences?

I don't know if this is the right place or if this is the right format but I'm extremely desperate right now. On phone trying not to flip the fuck out, sorry for formatting.

I broke up with my ex before my senior year ended, it was rough, but I realized that I couldn't be in a relationship as detrimental as it was and focus on college at the same time, so I ended it. It's was messy, things were said, threats made, nothing incredibly out of the ordinary. 

I guess she snapped. 

She threatened to expose secrets and claimed I abused her, in her words she "wanted me to suffer." Luckily I had it in writing (sent via text messages), so we quickly saved everything just in case.

What follows is months of blocking new numbers and prank calls, slowly dying down to nothing.

Until about 10 minutes ago, that is.

I typically ignore blocked/unknown numbers at odd hours (1 AM right now), due to what she's done earlier, but this one left a message. Curiosity got the best of me, I listened. It was Planned Parenthood. 

Does anyone know how I should go about this? I'm leaving for college this coming Tuesday... Plus I don't even know what's serious or not! Why would they call my cell phone at 1 AM with a blocked number? More importantly, if this is some sick prank, why did someone I care about go out of her way to make me miserable? How can I stop this?
<bot>: Ex harasses through various calls/texts/etc. Call at 1 AM, Planned Parenthood, no caller ID. Fake or not?
