My past haunts me

I'm 5 weeks, 3 days. This is my 7th pregnancy. I have one happy healthy 5 year old. I work in research and right now I'm working at an IVF clinic. Monday morning meetings terrify me because I hear about all these losses or cases where everything was going great but fetal pull never developed. Although this pregnancy is drastically different than any in my past I'm so scared of losing this baby 😢
