I'm so scared!!

2 months ago I started spotting, then I miscarried a few days after. I was about 4-5 weeks. I found out Monday I'm pregnant and in the night I started spotting. I'm so anxious and scared that I'll miscarry again. I haven't told my fiancé because if this pregnancy is ongoing I want to make it special for him. I'm so scared and I feel so lonely. I'm 4 weeks and 5 days today and I haven't bleed since I spotted two days ago. But I won't take of my sanitary pads just in case. I want to enjoy it but I'm so nervous😢
