So My period is almost 11 days late which is incredibly unusual for me. I've always had a regular cycle ever since i first got my period and before this the latest it's ever been is 4 days. I started Zoloft in early April a few days after my last period and I'm just wondering if anyone else who's taken an SSRI has expirenced an regular period after starting it.  Im trying to not stress about it but it's beginning to really concern me.
