Lovenox Users - Help!

Anthony
Hi everyone!
We are 21w1d and my wife has been taking Lovenox injections since we got a positive beta result. She has bruised a tiny bit here and there, but the last 2 days she is bleeding for a few minutes at the injection site. Yesterday a little blood drew into the needle, but not much. Also, her gums started bleeding a little bit yesterday. 
Has anyone experienced anything similar or have a professional opinion? Just looking to ease concerns while we wait to call her hematologist tomorrow. 
Thanks in advance!
