Your advice/help-perceived reduced twin movements

Jaime • Had our boy/girl twins at 35 weeks on September 30th. They are healthy and perfect!!!
Hi ladies, I just had an ultrasound last Wed, and both twins were great (30 weeks). I have an anterior placenta with my little girl and have always struggled with feeling her like the other twin (her brother). But, it truly seems like since my appt, her movements have decreased. I hear her on my Doppler with a strong heart beat. I am a worrier and just wonder what you would do? Maybe it's just that I'm running out of room and her movements are less? I would really appreciate your advice! I emailed my doc yesterday and they said come in and we will listen to her (which is what they always say I've come on for    at 26 weeks). Well, I can hear her for myself. I think I'm half exhausted with worry ...
