Testing anxiety!

Hi everyone im looking for some comfort I had my IUI on June 17th. I couldn’t wait to test on the 14th day, so I started testing four days ago. Initially, the line was very faint, but the last two tests are quite noticeable and seem to be positive. I’ve also been experiencing some cramping, and I’m so scared that this one will end in a chemical pregnancy as well. 😔 This is my second IUI. Before treatment, I had a chemical pregnancy and an ectopic pregnancy, and we’ve been trying for over two years, so I’m extremely anxious. 🥺has anyone had cramping at the very beginning and still carried to full term ?
