Pregnancy after PE

De

So my husband and I just went to my OBGYN today. We will be starting to try soon and based on my medical history of a PE (blood clot in the lung) they want to start me in lovenox as soon as I get a positive test. I am a nurse myself. I understand why I need to do this, just was disappointed that I am nervous about the twice a day injections and looking for support or similar situations that people have been through! Thanks much
