Wanting to be pregnant

Well I'm new to this blogging thing but here goes. I'm 27 and have a beautiful daughter who is now 13 months old. I had a pretty nasty pregnancy with her but she went to full term, and is a very healthy little girl. Well my husband and I really want to have another baby. So we started trying and ended up having two miscarriages back to back. So I've now had 2 regular cycles and have done some acupuncture treatments, hoping that this will help. So I'm 3 days away from my period and the HPT are still showing up negative. Is that normal even though they state that you can do them four days early? Starting to loose hope. Anyone else with these experiences?
