Does any believe in signs

In order to have kids I have to do <a href="https://glowing.com/glow-fertility-program">IUI</a> . My boyfriend was sick with cancer a while ago, before I knew him . so he froze his sperm before chemo and radiation. These past two years my boyfriend and I have been thru hell and back with infertility . So I Just had my third <a href="https://glowing.com/glow-fertility-program">IUI</a> done a couple days ago using the frozen sperm . Today my sister in law texted me saying she had a dream I was pregnant and her sister is pregnant so she said we were pregnant during the same time together. I just can’t get over that is that weird or ???
