Scared, confused, and not sure what to think

Okay, idk what’s going on. On 2/13 I got a faint positive at 3w6d roughly. Called my nurse and she said to come in for blood work, early I know. But I did as she said. Went in, hcg levels were low, but within the range. She said to come in again Monday and Wednesday for more blood work to see where the levels were. I went in Monday 2/18 and my hcg had increased, but she said they were still low. So she said to come in Wednesday (today) for more blood work, so I did. I should get the results back tomorrow. I’m scared baby isn’t sticking. I’ve read about women being in the “15%” of slow/low hcg levels and having normal pregnancies. This is my first pregnancy ever. I have not had any bleeding or any symptoms of a miscarriage or ectopic pregnancy. I’ve had normal pregnancy symptoms. I am taking prenatals and doing everything as I should. I’ve been trying for a year to get pregnant, and I finally got pregnant. Are there any mamas out there that have had this scenario or something similar? What were your levels and what was the outcome of your pregnancy. I don’t want to lose it, but I just wish something would happen whether I miscarry or not. The guessing game is not fun. Just need some insight. I’m trying my best not to stress, but it’s kinda hard when I’m not sure what my body wants. I also think maybe it’s just taking my body to realize what it needs to do since it is my first pregnancy. Please help:(
