Spotting at 9wks?

This is my first pregnancy. We did ivf and i didnt have any symptoms at all so far except literally eating for 2. I started spotting today which was pink-a rusty red/brown color. It’s light not heavy. I also started cramping mildly which i guess caused the spotting. When i dont cramp there is no spotting. I just want to make sure its nothing to worry about? I know spotting is normal in early pregnancy but it being my first after trying for so many years im a bit nervous now as im experiencing it.
