Welcome to Healthcare magic forum.
Please do not panic.
If you are having menstrual bleeding right now on or near your usual expected dates then most likely you are not pregnant.
If you have missed your period or experiencing little or irregular bleeding or spotting then the chances of you being pregnant are more likely.
tests results are subject to content of the hormone hcg in urine and vary depending on the time of day, technique and days of gestation.
Please avoid such high risk behaviour till you are an adult and as for now you may get a blood beta hcg
or an ultrasound
abdomen to confirm the present situation.
It's always better to confide in your parents or any adult relative before going ahead with medical consultation.
All the best .
