Missed period on birth control, with condoms

[Jennay22]

Ok so I'm officially 12 days late for my period. I take birth control, and it usually takes me 4 days into the sugar pills to get my period, so I guess I am 8 days late. This has never happened before though.
I had unprotected sex last month, but took Plan B the day after. And then I got my period.
Since my last period, I was extremely on time for the pills every day, but then I got random bleeding in like week 2 for about 4 days. Then i had protected sex only. I havent been under a severe amount of stress (ive had way worse).
I took a pregnancy test 3 days ago. It was negative.
What could be the cause for my missed period? Is there any chance i could still be prengant, even with the condoms..?

Anytime you have sex you have a chance of getting pregnant. Birth control pills and condoms greatly reduce the chance, but there is always a chance.

I would recommend taking one more test and if that one is negative I would chalk it up to your cycle being weird after the morning after pill.

There is a chance you could be pregnant but it's very unlikely. When you use birth control and condoms it decreases your chances which is why I prefer using both of those things when I have sex. Sometimes you can miss a period when you are on birth control. I've missed a period while on birth control and was pretty paranoid about it but the gynecologist told me that sometimes this can happen. They told me to take a pregnancy test just to be safe.

Since you've already taken a pregnancy test you really don't have to take another one. But, it might help you feel less stressed out if you did take another test.

I have also heard that when you take Plan B while on birth control it can really mess with your hormones as well as your period so that is very likely the cause of the missed period.
