i need advice, i'm afraid it wont come

[very confused]

I finished my period around August 23rd, I had sex (protected sex) with my boyfriend at least 3 times during that week. I also have this application on my phone that tells me when I should be getting my cycle, but I don't feel any of the symptoms & I usually have bad symptoms. According to my phone, I'm suppose to get it tomorrow. I'm so confused, I'm hoping the application may be wrong. Should I be worried?

Well.... Being worried or stressed that it won't come isn't going to help any. Stress can cause a delay in your menstrual cycle, so try and relax. You had protected sex, luck is on your side that you are probably okay.

If you don't start within the next couple of days, test.

Stress can cause delay. As you mature the problems you associate with your cycle may cease. So relax, make some nice ginger root tea and don't stress about it.

I agree with the ladies. The stress will cause it to be late then the stress will just continue to get worse. I'm sure you'll be find.
