Lost a pregnancy a day shy of 5 weeks in July, late by two days as of right now...

My period was due Monday, it's now Wednesday (though it's early in the day so I wouldn't say I'm three days late yet). I've had very sore/tender breasts and nipples for a few days, which usually only happens for a day or two the week before my period and it never this bad. I've also been nauseous for about a week, though I haven't been vomiting.

My first period after the pregnancy was a normal 7 days but my period last month started 9 days early with spotting for about four days, then bleeding for 7, which is what my periods were like for a few months before I got pregnant in July. My doctor said that it was fine for them to be like that, since I was able to get pregnant everything is working fine down there. Now I'm torn. I'm incredibly anxious and want to test again but I also want to wait because I feel like I'll just get my period a few days late and feel disappointed and foolish. I'm also afraid of losing another pregnancy early. I was 9 days late the last time I tested and only knew for a few days before I lost it.
