Spotting before 1st beta 13dp5dt

I am 13dp5dt and have my first beta tomorrow. I started spotting this morning (reddish-brown). This is my first transfer (modified natural) and I’m taking progesterone suppositories 2x daily. I’m feeling both pretty defeated and still naively optimistic.

I’m looking for similar stories with a happy outcome, similar stories with a disappointing outcome, and/or internet hugs. I don’t think anyone in my inner circle, even my husband, truly grasps how lonely and gut-wrenching this experience is (except for my friend’s wife who just had her first transfer - and I don’t wanna bother her with this!).
