Looking for advice to calm me

So, my doc is a m-f guy and it's Saturday. I know a lot of women seek advice on here when they can't get to the doc, so here it goes. I found out I was pregnant a little over a week ago, according to nurture I am 5w5d today. I had a lot of cheapie tests so I kept testing every day to see line progression and after the first few days it seemed like it didn't progress much for like a 5 days. Then this last Thursday (2 days ago) it looked quite a bit darker, but here's the kicker, that's when I started spotting. Spotting is mostly pink and some red. Now yesterday and today my lines are even darker but I'm spotting pretty heavy and have AF like cramps! I'm so nervous. I had a miscarriage at 6w3d in July after having tried for a year to get pregnant. Please let me know if you've ever experienced anything similar or any input. Thanks
