Anyone similar to me?

So I’ve had chemicals before and one time I had a “period”. Like normal, it was 5 days but not really clotting and not as heavy. Then I turned out to still be pregnant but still lost it. This month I’m in the same situation that my period isn’t heavy at all and no clotting. I’m on my “last day” and my boobs still hurt and I just wonder if it’s the same situation. I thought I had a faint positive the other day but now I don’t see anything. But the last time I was pregnant I had a positive then that “period” started and it wasn’t positive while I bled. Then a week after my “period” I tested cause I felt funny and it was positive. So I’m not sure what to do. I want so badly for this to have a great ending and I be pregnant. But I just worry too it’s all in my head.😩
