Hi, thanks for using healthcare magic
would require sperm to come into contact the ovum and this would require either the sperm being placed in the reproductive tract medically or by intercourse.
It would be difficult to become pregnant otherwise.
Despite this reduced chance, if you are concerned that you are pregnant then you may want to consider performing a home pregnancy test.These are usually accurate, they detect the level of HCG in the urine.
HCG is the hormone that is produced during pregnancy.
There are other causes of delayed periods such as emotional or physical stress
(such as illness), abnormal levels of thyroid
hormone, high levels of prolactin
hormone, inadequate diet, excessive physical activity and PCOS (polycystic ovarian syndrome
If the pregnancy test is negative then you can consider visiting your doctor for an evaluation.
I hope this helps
