Trying to stay positive...

Yesterday I had another OB appointment which was 2 weeks after my anatomy scan. I remember thinking she saw something wrong because she got really quiet and was staying in one area for a really long time but of course she couldn't tell me anything, that's for the Dr to do. Well he starts by telling me they didn't like the images of his heart.. there were some abnormalities so he's referring me to the high risk dept for a special scan of some kind to get another view. He did say baby could've just been in a bad position, but would I have to go to high risk if he really thought that? The next thing is he told me my placenta wasn't fully attached and put me on pelvic rest to not cause further detachment but im nervous about that because the day before my appointment my parter and I rearranged the bedroom and I did so much of what I was now being told to avoid! Why didn't they call me before my appointment? So much could have happened or changed in those 2 weeks and I don't even have an appointment for the next scan so who knows when that'll be! Im so nervous and scared and against better judgment I went to Google and apparently a partially detached placenta could lead to preterm labor. I'm almost 27 weeks, he would be so tiny :( and if he does have a heart issue... I wish I had more answers I cant stand this
