Help ladies please

So being told basically my whole life I’m unable to get pregnant a true miracle happened....on Monday it was confirmed by blood work that I’m actually pregnant 🤰 😊😊😊

I can’t get into see my family doctor to start prenatal care until Tuesday (19th). This wait is killing me. I’m so nervous being 37 and pregnant with my 1st is just unbelievable.

TMI

Monday night I had brownish discharge when I went to wipe. Which continues into yesterday evening then changed to a very watery pinkish color. Anyway early this morning had to wake up to go to the bathroom and when I looked on the TP it was very very dark blackish red 😳😳😳. I have slight cramps in the middle of my lower belly which are not as intense as period cramps. I e been exhausted, my belly sounds like thunder/gurgling, and I’m hungry 😋

Please help!!!! I’m guessing I’m 6-7weeks as the first day of my last cycle was January 1st. Please help, maybe it’s just me overthinking and being in shock and well googling really doesn’t ease my mind to get me through until Tuesday.
