5 weeks and so paranoid about MC

I am 5 weeks today. I already posted about my breast tenderness going off and on, and many of you said it was normal. But today it’s off again and I just wiped and had a small amount of brown tint in my discharge. I realize this is normal as well, but I can’t help but feel paranoid that my pregnancy is going to end in a miscarriage. I had one about 10 years ago when I was with a different partner. But I’m afraid of the same fate. It’s hard getting excited about this pregnancy because I’m so nervous that it won’t stick. My husband keeps reminding me to stay positive and that the negative thoughts will only make it worse. I just wish i had consistent symptoms and was further along already. I have my first appointment next Friday at 6 weeks, so I’m hoping they’ll run some blood tests and give me some peace of mind. Just needed to vent. 😩
