paranoid? or...

So when i was 16 i had a terrible miscarriage at 24 weeks. Had my son after that in 2011, and my daughter in October 17. Both healthy pregnancies and babies. I am pregnant again, due November 30th. This pregnancy has been terrible so far. Nausea, Vomitting, extreme fatigue, ligament pain all the time, my boobs so sore etc..definitely felt pregnant. Also im being monitored a little extra close because my uterus lining is so thin I guess from just having my daughter 6 months ago and i havent fully healed from that yet.. I woke up 4 days ago and every single one of my symptoms had subsided. So i figured, probably just because im moving closer to second trimester. Then, i started spotting the next day. I am still spotting. light pink, not red, not heavy, no cramps. I just feel seriously like im not even pregnant anymore at all. My OBGYN said theyd see me Thursday for an appointment and if im concerned to go to the ER. I havent gone to the ER because 1. if i am miscarrying, they cant help me until the labor part comes on/ or stop the baby from passing because im too early, and 2. although im SO anxious, part of me says im just being over paranoid. I took a pregnancy test, to see how dark the lines would be today, compared to tomorrow at same time, maybe id notice a difference such as my hormone levels decreasing? . Am i driving myself crazy for no reason? or do you guys think i may, in fact, be starting the miscarrying process? I'm just confused. Thursday cant come soon enough! I have a personal doppler and cant find the heartbeat myself, but im only 10 weeks and 4 days. I NEED a peace of mind ladies! 💔💗
