Ease my mind

I got a positive test Thursday (one of the cheap strips). It was faint but there. I then got two digitals and a blood draw all positive. It’s my first so I’m really scared to lose it. I have PCOS and had to take clomid to get here. The doc said come back next week to check my hcg levels, I was 47 on Thursday.

That would be like four weeks this week. So I tested again this morning on the little strip because I thought the line gets darker when you have more hcg which I should since it’s been two days. But it was just as light as the first.

Should I be concerned or do those strips suck haha
