Sad and confused

I’ve been spotting since last Wednesday, it went from light to dark to pink to brown and now to red with the passing of small blood clots…I’m around 9-10 weeks and I’ve had a miscarriage last year in September and I’m terrified that I’m going thru another one…I’ve read on abt the placenta being attached at this point which can cause bleeding and I pray that’s all it is…not to mention I’m cramping like I’m having a period…I’m dreading going to the doctor or ER and they tell me what I really don’t want to hear, is there anyone out there that have been through something similar? I know at my age(38) my body is different and things may not be as easy when I gave birth 13 yrs ago…im just so scared! Please someone help me
