Spotting & Cramping at 5w4d HELP!

Whit • 1 Angel baby 👼🏼 Rainbow baby due April 2nd 2018 🌈
I tested Thursday + then again Friday + on 3 tests then Saturday morning I started spotting and cramping and haven't stopped. I tested again on Sunday morning just to calm my nerves and it was still +. It's mostly brown and but some pinkish-red constantly. I'm wearing a pantyliner and everytime I pee it's there when I wipe. Called my Dr. Saturday and she said as long as I'm not vommiting or have a fever I'm okay and to wait until Tuesday (today) to test my HCG levels. Went in yesterday for bloodwork and go back tomorrow for more bloodwork. I have sore boobs, 24/7 nausea, dizziness, headaches and insomnia. Anyone else with me? I'm so scared and have been trying to remain calm and rest but it's so hard and all I want to do really is cry.
