Hello Levi's mommy, its good that they put you on bed rest, your measurements are not 'too' large but they normally work out the risk compared to the size of the baby, so at 7 weeks the baby is not too big....... however i had one about that size (a little bit smaller) at 8 weeks and im now 20 weeks and waiting to see if mine has shrunk (as it continued to grow to a large blood clot) i hope everything works out well for you, best thing you can do is listen to docs and try and get school on side to help, problem is a lot of people do not know about SCH, my doctors didnt even tell me thats what it is, and have just continued to monitor (scans, consultant led pregnancy) but didnt tell me to rest or no sex etc!!!there are a lot of positive outcomes so try not to worry too much.xx
