I think I am pregnant?

Hello.. I need some help. I had an awful Misscarriage about 6 months ago. I was 3 months pregnant. It has been the farthest thing from my mind to try because my loss was so bad. I am due for my period on Monday. I have been napping and my hurt. I have some mild cramps. Just like my period is coming. I am drawing a blank on how it was last time I was pregnant. I took a test a couple days ago. I know it was early and it was negative.... Tonight I took another one and there is the slightest line.. VERY light.. Can I be pregnant? I compared it to the one 2 days ago now that they are both dry and the one def has a slight line when the other doesn't have a thing. I am going to retest in 2 days when I am due. But these cramps and back aches worry me.. Isn't it to early to feel these..
