I appreciate your query
The cyst in the right adnexa could mean one of many things.
Number 1 - the bleeding after a positive pregnancy
test could mean that it was an early spontaneous abortion
, and the adnexal cyst
, could be an early corpus luteum
, that supports pregnancy.
Number 2 - it could be an ectopic pregnancy ( pregnancy outside the uterus
- inside the tubes or ovaries
Number 3 - it could be an incidental adnexal cyst alongwith a pregnancy.
You need to attach the complete report to arrive at a conclusion.
Also , am sure a repeat scan in some days, or estimation of blood B - HCG levels will provide a clearer picture.
All the best.
