Any advice for being worried 😭

An

So we've been TTC for about two years and I just got my BFP. I'm super early, like I think I got my BFP at 3 weeks, and calendar says I'm 4 weeks and a few days (the calendar on <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> didn't link with glow and I've been thinking I was further along). I was feeling extremely sick and terrible then two days ago I still have some minor pulling and cramping like I've been having and burping, some headache, but nothing like i was having before. Is it stupid that I'm worried I'm not pregnant, like I know I am, I haven't cramped bad or bled or really felt "not pregnant" but since my symptoms went down I've been worried that my baby will go away. I can't calm myself either. It's like I get sick occasionally but nothing like the first few days and then I worry myself until I start feeling sick again and I'm like there you are baby. I just could use some reassurance ladies, please, all we want is to start our family and we finally have a baby growing.. it terrifies me that I could lose it.

Test have gotten darker since this.
