I have taken 7 pregnancy test all positive and my period is 3 weeks late. Could I be pregnant?

Yes, you could be.
See a doctor.

You've had 7 positive pregnancy tests?

Congrats, you're pregnant.

A false negative is very common, a false positive isn't. You've had 7 positives, so it's time to see your doctor, start taking prenatal vitamins, and start taking care of yourself and baby.

Why would you even question 7 positive pregnancy tests?

Because I've heard of false positive and chemical pregnancy. All in all I'm a worry wart.
