General Hospital” spoilers reveal that Nelle Benson (Chloe Lanier) will stop at nothing to drive carly Corinthos (Laura Wright) off the deep end. Next week's “GH” spoilers hint that Nelle turns up the heat on her unborn baby's grandmother, but it will backfire, and rumors says she’ll lose her baby! That’s when Nelle takes her awful scheme to a new low.

Nelle still intent on wrecking Carly

Nelle came to Port Charles with an agenda almost two years ago this August. She came to town determined to destroy Carly Corinthos, her adopted sister. Nelle wrecked Carly's marriage to Sonny Corinthos (Maurice Benard) but luckily the two found their way back to each other.

“General Hospital” spoilers [VIDEO] remind that Nelle also wormed her way close to Josslyn Jacks (Eden McCoy) too. And now Nelle has Michael Corinthos (Chad Duell) on the hook because she’s carrying his child.

Carly vs. Nelle about to explode

Longtime “GH” watchers know that nobody messes with Mama Bear Carly and her cubs. But the young woman is stupidly fearless when it comes to tangling with Carly. It seems she's on a suicide mission because she’s messing with the wrong woman.

“General Hospital” spoilers [VIDEO] see Nelle’s gaslight plan using Carly's dead son Morgan Corinthos (Bryan Craig) is fast pushing her over the edge.

That seems like the lowest Michael's baby mama can go, but there is something much worse ahead.

Everyone thinks Carly is cracking

Thanks to Nelle’s antics, those closest to Carly are beginning to wonder if she’s having another mental breakdown. Her awful plan is succeeding. Even Carly is questioning her own sanity and that’s a huge feat for such a strong woman like Carly.

“General Hospital” spoilers for this week show Dr. Kevin Collins (Jon Lindstrom) put Carly on meds. Unfortunately, that opens a new avenue for Nelle to mess with her. That schemer has a history of tampering with meds.

Carly’s support system fails

Ordinarily, Jason Morgan (Steve Burton), Sonny, and Michael would be watching out for Carly, but they are all distracted.

Jason is chasing Henrik Faison while Sonny and Michael are worried about Mike Corbin (Max Gail) so this is a perfect time for vindictive Nelle to turn up the heat.

“General Hospital” spoilers buzz says Nelle's hate for Carly is unprecedented and she will stop at nothing to drive Carly insane. Nelle let her emotions rule and it finally backfires. While scheming, Nelle puts herself and baby in harm’s way and gets into an accident that causes a miscarriage.

Nelle loses the baby, blames Carly

“GH” spoilers wonder if Nelle is so depraved that she would use the loss of her baby against Carly. “General Hospital” chatter says Nelle sets Carly up, making it look like she tried to harm Nelle and, in the process, caused the death of her unborn grandchild. It will be Nelle's word against Carly's but since Nelle has been slowly driving Carly off the deep end for months, it doesn’t look good.

Nelle paints herself as the victim of crazy Carly. Will anyone believe Carly or will Nelle win and use the loss of her baby to draw Michael closer and win this sick game? Stay tuned to ABC for new “GH” episodes and watch for more “General Hospital” spoilers.
