Rubella exposure!

Okay so im 9 weeks pregnant. I had rubella vaccination as a child and im now 26 and in my pregnancy with DS in 2015 there was no reports of my immunity being low.

So today I picked my DS up from childcare and a child has now been suspected of having rubella! Child is under 1 so has not had the vax yet. The child is not in the same room as my DS but kids tend to cross over rooms but from what Ive heard this child has never associated with my child..

I have a midwife appt next Wednesday.. should I wait until then as they will draw bloods anyways or organise a gp appt tomorrow?

Do you think I should worry as im currently packing my dacks!!
