Help levels are weird.

So my levels were 15.5 first draw, 13.8 second draw, and then 13.8 third draw. They were all draw 2+ days apart and I just want to know if this is normal. Or if I still can have a healthy pregnancy. I know it's most likely a chemical but just wondering what you ladies think.

Side note: I lost a baby at 12 weeks and then 7 weeks later found out i was pregnant with this one so I'm already nervous. It was def another pregnancy because a week before my possitive there was absolutely no line. I also have very poor circulation. I'm not sure if that would matter.
