Is this normal for my evening pregnancy tests to be darker than my morning ones?

Ky 8-15-17👼🏼 & 10-28-17👼🏼 Pregnant with my🌈💕

I'm just worried this round because I had two prior miscarriages. Today is 14 days since I had my trigger shot and the last test I took this morning at 9 am with second morning urine and only a two hour hold. Why are my morning tests lighter than my evening ones. Is that normal?? Every little thing scares me because of having miscarriages. I'm almost scared to be excited. I'm scared to sit a certain way, scared to laugh, move certain ways, ride in our truck on the bumpy country roads, scared to eat certain things. It just awful how worried you get about each and every little thing after you get pregnant after a miscarriage. I just hope and pray we get to keep this baby. My appointment is on Monday with my specialist to confirm pregnancy. I'm also on progesterone suppositories two times a day and have had some pinkish spotting which scares me and hopefully that's just a side effect of the suppositories. Is this normal for my morning tests to be lighter than my evening ones? Also if you would say a little prayer for me that this will be a healthy pregnancy this time it would be greatly appreciated and I will return the favor💕
