pregnancy rebif

I’m 16 weeks pregnant. I found out at 5 weeks and stopped rebif straight away. I asked my midwife at the time if I should have any concerns regarding rebif injections during these first few weeks to which I was referred to ask the same questions when I went for my 12 week scan. So I did and no answers were given. Today I received a call from the hospital asking me come in next week to discuss said concerns. I’m unsettled after today’s call and wondered if anyone had any experience of this?
