Hello, Thank you for asking your query at DoctorSpring.
There are likely chances that you are not pregnant. You had sexual intercourse not during the fertile period.
Ovulation occurs 14 days after your period starts. Ovulation is nothing but a process where egg is released, and there are possibilities foe fertilization to occur during this time if you have sex. Therefore, this is your fertile period, starting from one or two days before ovulation to 24hrs afterward. But, each womens cycles vary from one another, I suggest you repeat Urine pregnancy test after a week.
By this you will know if you are pregnant, I suggest you visit a gynaecologist.
Hope this helps. Please feel free to ask follow-up questions
