Hi,
Welcome to the forum. I am really glad to help you out. Pregnancy needs to be ruled out in view of the symptoms which you are going through which are suggestive of pregnancy. I would suggest you to get your serum HCG levels estimated since this is more specific than urine for pregnancy tests & it gets elevated in blood much early (around 10 days after the implantation of the zygote, formed by the union of an egg and a sperm).
The urine pregnancy test is usually done around 1 week after the missed periods. The HCG (it is a hormone) levels rise only in pregnancy and its presence will confirm the status of your pregnancy. However, you didnât have sexual intercourse and your boyfriend had done fingering. The sperms are very fragile and if they are exposed to the outside environment, they die very quickly. Hence, this considerably lessens the possibility of a pregnancy. Please do consult a gynecologist for the same. I sincerely hope that helps. Take care.
