Kinda? Before starting antipsychotics my BMI was too low for a period, but then Seroquel lead to eating and sleeping and a healthy BMI and a period (irregular, 3-6x a year, but it was there), and for similar reasons Topamax made it go away until I stopped it and got back up to a good weight. I know Invega, Risperdal, Haldol, etc. can affect prolactin levels and therefore cycles, but I've never noticed this effect in myself, but between ED&relapses, birth control and switching, and effects of bipolar that probably affect hormones (like sleep, stress, diet) the closest to a "regular cycle" I've had was 4 months of a 3 week cycle consisting of 10-14 days of bleeding and 10-20 days of not but still feeling PMS-like symptoms.
There has been at least one case where Gabapentin was suspected of stopping periods.

Three months after the initiation of gabapentin therapy (1800 mg/day), the patient reported complete cessation of her menses. Based on hormonal tests, her gynecologist concluded that her amenorrhea was secondary to gabapentin therapy. The patient was weaned off the gabapentin over 6 days with return of her menses 2 weeks later.

But if you're only a day or two after you expected it, I wouldn't think much of it (although after what I wrote about my cycle, of course I wouldn't). A period is only considered "late" if it's 5+ days after you expect it, or missed if there's no flow for 6+ weeks.
