Bleeding after sex after ivf

Hi I was wondering if anyone has bled after sex weeks after a failed <a href="https://glowing.com/glow-fertility-program">ivf</a> cycle? I found out our <a href="https://glowing.com/glow-fertility-program">ivf</a> didn’t work on the 21st July and ever since I have bled a bit after sex. Is this normal or should I be concerned?
