7 week symptoms tapering off

I wanted to post this because my symptoms started tapering of at a little past 7 weeks, and it started to freak me out! I googled it and read that it can be normal or it could mean a miscarriage.  I just wanted to tell anyone concerned that it is scary as shit but it can be normal! I for sure thought there was something wrong, at 6 weeks my boobs hurt like crazy, I was CONSTANTLY nauseas, I was so exhausted and literally I woke up one morning and none of those symptoms were that bad, and as my 7th week went on the symptoms got less and less.  But today at our 8 week ultrasound we saw both our twin babies going strong! So tapering off of symptoms can be very normal, don't stress out, I was stressed for a week before this us, and it was so pointless! I hope this comforts someone worrying about disappearing symptoms!
