I have endometriosis and have had countless transvaginal scans/ ultrasounds over the years and also had a laparoscopy in October.
I'm 14 weeks pregnant and have had 4 scans in total so far, two private and 2 NHS. Today was my NHS 'dating scan' all good with baby and then Sonographer casually asked if I'd ever had an ultrasound before, I laughed and said yes, countless and she asked if I'd ever been told that I have a heart shaped/ Bicornuate uterus. I said no, no one has ever mentioned anything, in fact in all of my pregnancy scans so far, every sonographer has said how healthy and normal everything, including my uterus(!) has looked.
I had no idea what this means so was worried and she said 'oh don't worry, it'll just mean the baby will be stuck in one part of your uterus
and that it might end up being breech resulting in c section.
I got home and did some research/ googling (which I know you should never do!) and obviously got lots of horror stories and stories of people miscarrying in their second trimester due to it/ having really prem babies etc.
I rung my midwife up and told her what the sonographer said. She was confused as to why I'd just been told that but no details (I.e how severe mine is etc) and sent on my Merry way! She said I needed to ring the antenatal unit up at the hospital and ask for a consultant to ring me back to talk through my ultrasound report.
So I did and a midwife went and spoke to a consultant and showed him my scan report. He wants me to go in in 2 weeks time at 16 weeks for a scan and consultation with him and then every 2 weeks after until I think 20 weeks? 
I'm sat here now so worried, I was so happy a few hours ago thinking everything was great and DH and I were so excited and looking forward to this baby. I feel angry that if I hadn't of pushed the issue, we'd have just been discharged and wouldn't have been seen again til 20 weeks.
I get there's probably nothing they can really do at this stage but for whatever reason I'm now consultant led and he wants me to come in now every 2 weeks. None of that would've happened if I hadn't of listened to my gut and rang my midwife.
Has anyone else had a heart shaped uterus and had a successful pregnancy?
