I recently had my usg done and it shows that my right ovary is mild bulky with increased thickness and echogenecity of central stroma in bilateral ovaries. No collection seen in p.o.d. my right ovary is (36×19×28 cm)11cc and left ovary (27×23×15 cm) 5 cc. Usually my periods last for 4-5 days but this time it lasts only for 2 days. I had sex 3 months ago and I took my pregnancy test through kit 2weeks ago and it says positive but the beta HCG test says it's negative (1.02). I am confused why my periods lasts too short ? Wheather it is because of pcos or pregnancy? I am attaching the reports. Please let me know about the problem
