10 weeks - blood when I wiped

Da
Hi ladies, I'm ten weeks pregnant following my battle with <a href="https://glowing.com/glow-fertility-program">IVF</a>
All has been going smoothly. This morning I woke up with really bad nausea and I had a bit of blood when I wiped.
I went back to check about five minutes later and no more blood. 
Do I need to freak out or do I need to stay calm?
