ugh ugh ugh

So I just happened to find out that I have rh negative blood this is something I have never even heard about until a couple of days ago even though I have a two year old daughter I don't know or even care why I wasn't told about this or given a rhogam shot bc at this point I just want to know the solution.  If I am rh sensitized could this be what just caused me. To have a chemical pregnancy and will I be able to even have more kids?!!! My love is rh positive (he thinks) I'll find out for sure soon but ugh I'm literally flipping out after reading some of the stuff about this.
