Brief Answer:
No,the chances are very less.

Detailed Answer:
Hi,

Thanks for writing to us about it.
I can understand your concern here.
The chances of urine hpt false positive for four times are very less.
Usually with good and sensitive hpt test ( if done properly) the chances of false positive are less.
A urine pregnancy test detect hcg hormone in urine which is a hormone secreted during pregnancy by placenta.
So some drug which contains hcg hormone and tumours secreting hcg hormone can cause false positive results.
To confirm the result you can go for blood beta hcg test which is more confirmatory test.
Hope it is useful, feel free to discuss more.

Brief Answer:
Get your pelvic ultrasound scan.

Detailed Answer:
Hi,

Nice to hear from you once again.
If your beta hcg blood test is positive than you are pregnant definitely.
You should get your pelvic ultrasound test done to confirm and see the pregnancy.
In ultrasound they will find a gestational sac and fetal cardiac activity.
Hope it is useful.
