Late period on the pill after food poisoning

I've been on the combined pill for about 4 months now and have been strictly following my pill taking regime. However, during the second week of my active pills, I had a bout of food poisoning with one or two cases of diarrhoea. I wasn't sure if this affected my pill absorption at the time, but I had spotting (dried brown blood and some fresh red blood) a few days after which lasted just over a week. So now, I assume the food poisoning caused me to "miss" a pill/s. I've been very regular with my period since I started taking the pill but this month it's late. I didn't have any sex with boyfriend the week I was sick and when we do we use a condom as well so I'd hope the chances of getting pregnant would be very low anyway. I was just wondering if this is normal and if the "missed" pill caused a light period to come early?

Any helpful advice would be appreciated! Thanks!

Welcome to ehealthforum,
If you had vomiting within few hours of taking the birth control pill, there are chances that it might get vomited out and act as 'missed pill'. Using barrier method along with taking pills gives you higher protection. Increased intestinal motility can at time hamper the absorption of the pills. Wait and watch for your periods/withdrawal bleeding which might get delayed due to stress of infection and antibiotic use. If you suspect pregnancy chances or hormonal imbalances, consider visiting your doctor/gynecologist for further evaluation and assistance.
Take care.
