46 and pregnant

I will be 46 in February and 10 years after my second child we find out we are pregnant. My DH and I were not trying to get pregnant, this was not in our plans. Our first two children we had help getting pregnant with clomid. We are both very overwhelmed. We have read a lot over the internet, false positives and perimenopause, could this be Menopause?Reading about the high risks of natural pregnancy this late in life, it is scary. We go to see our GP on Friday and my first appointment with an OBGYN isn’t until the 11th. According to my charts on this app we are in the 6th week. Any advice is most welcomed!
