Went to ER last night: pelvic rest?

Ashleigh • Happily married mommy of two :)
I was having spotting and cramping so about 10 last night we went to ER. Apparently everything looks fine though. Hcg has jumped to 51,032 and baby heart rate is at 113 bpm. Couldn't see baby yet but he/she is there and doing great. I am 7 weeks today and that's what I'm measuring at with hcg levels and such. Got put on Pelvic Rest...so apparently no sex or pretty much moving more than I have to. They don't even want me lifting my other child who's almost 6 months. That will be hard :(
