Sensitive subject 🤷‍♀️

Has anyone ever experienced a phantom pregnancy? The reason I ask, is I’ve been having movement in my tummy the past week or so now (mom of 2 already), had a period on the 9th Feb and thought that I was out (as we do) so it didn’t even cross my mind... well last Monday I started to feel flutters and thought nothing of it... it’s getting stronger on a daily basis (I can feel it) and I’ve got this tummy out of nowhere!! I am usually a size 14, curvy but usually have a flat stomach. It’s grown since last week, but my doc thinks ovarian cyst... I wasn’t convinced so I got into the midwife for a Doppler... she couldn’t detect a heartbeat and said that she wasn’t sure what it was... so now I have a scan booked for a few weeks time... I’m just very confused. The bloat is heavy but all I can think is phantom...it wasn’t even on my mind that I even could be... I’ve heard of phantoms early on but the belly you are about to see is not “a few weeks”. Any advise welcome xxxx not even ttc until after April
