Just before your period, if you do a pregnancy test and the result is positive, it could be that you indeed might be pregnant. This can happen, because of the production of hCG by your body which is detected by the test. You can still have the impression of a period being on the way and yet, hCG may occur in early pregnancy. If you have doubts about the result, you can verify it by performing a second test a couple of days later.

Considering the beta hCG value of 0.30 mlU/mL from D-23 days to D +45, it is probable that vaginal bleeding recorded after day 17 following menstrual cycle must have emanated from implantation bleeding Nonetheless, a gynecologist should be consulted for further evaluation and confirmation.

A pelvic lump is a surgical emergency, and you should not wait to visit a healthcare provider for appropriate medical examination.
