My Home pregnancy test

Yesterday morning I went to CVS to buy a home pregnancy test because I didn't get my period and I had sex with my boyfriend like the days I was supposed to get pregnant so what happen was up I bought a test first response is the best test ever made I came home and I did the test I was so shocked to finally find out that I was pregnant I was crying a little I am in a medically call them my boyfriend and him and informed him told him I was pregnant. I noticed he was a little stressed out about it and Then a few minutes later he told me he had to go to work I told him OK just do not stress out and please think about it because we're going to be parents he told me that he will. As soon as he got out of work he texted me telling me he was going home I told him OK and I noticed he was more calm about me being pregnant I know my boyfriend since middle school we were always close and I know his loyal and faithful to me he loves me like crazy so I was happy to hear him not stressing out and made me feel really calm inside so I didn't stress out like I thought I would I'm so happy I'm finally pregnant I keep talking to my baby is telling him or her that I'm gonna protect them with my life even though I know my baby can I hear because I'm like four weeks and five days
