Hi, was just wondering if anyone has had this happen before? I had a transvaginal scan to check for PCOS. confirmed polysistic ovaries but during the scan the sonographer found a gestational sac with no contents. They advised me to take a pregnancy test but I’ve tested for 4 days and all negative so far. Have GP appt 13/02 but I’m just really stressed out about it all. I should mention my periods are all over the place and I haven’t had one since November. Has this happened to anyone before?
