Being Pregnant and on Heparin

Natalie
Hiya guys,
​So I just found out I'm pregnant, which is all super exciting. However, there's a niggly worry in the back of my head as at some point during this pregnancy I am going to have to start injecting some form of blood thinner due to high risk of DVT. Has anyone been there? Can anyone put my mind at rest? I don't want it to take over my pregnancy. Me and my partner are so excited!!
