Spotting and bleeding?

Amanda
Anyone else experiencing spotting? I didn't with my other two but this one I have been. Doctor is running my blood work and it has been good so far, but the spotting is increasing. Cramps are more intense at the end of the day. Doctor also says this happens in 40% of pregnancies and not to be worried yet, but I can't help it. I also got a rhogam injection since I'm Rh negative. Hoping and praying this doesn't lead to miscarriage. Anyone else dealing with this?
