Positive pregnancy tests

Hello! My name is Amanda and my husband and o have been ttc for 2.5 years. I got pregnant on March and sadly it ended in miscarriage. I finally got a positive on Friday!! The line is getting darker and I'm so excited. I have taken like 7 tests and they are all positive. I am a little worried because with ever one of my pregnancies I would spot around the time I start my period and the spotting would last for 4 days. I have had no spotting what so ever and I'm worried it's not normal. Has anyone gotten pregnant and had no spotting at all I'm the beginning? I attached a picture of the most recent test taken today.
