Pregnancy scare! Please help

[Panicbox]

I'm a 19 year old female and have diagnosed myself with many illnesses in the past.

Now I fear I am pregnant!

Iv been on the microgynon pill for 2 years.
Iv never ever missed a pill

I had light periods in may and June

My period in July was quite normal just a bit shorter than normal

I'm scared that the changes in bleeding could mean im pregnant!

Take a test, only way to ease your worry

Agreed, that's the only way to know for sure, but the odd lighter period is generally regarded as normal, even if someone has been regular for 10 years.
