I would love for some insight

I am currently a nervous wreck. This is my 4th child. I had miscarriages before but later in the pregnancy. I am currently 5 weeks and 1 day. Yesterday I experienced some cramping in the bottom of my abdomen (kind of where a c section scar would be). I also felt a couple of times a little pulling feeling in my vagina. I went to the bathroom I had like three specks of blood that was kind of bright pink. Today I woke up and the pain was gone in my abdomen but now I have like dull- cramping pain on the right side that comes and goes. But it’s not a pain that stops me from what I am doing. However, I still know if it is present. I called my doctor yesterday and he told me last Monday on the 6th my progesterone was 19.1 which is beautiful. He didn’t think it was necessary for me to go to the ER. However, he did say that he was going to re check my progesterone levels on Monday. I’m kind of nervous and would love to know if anyone had a similar experience and what there outcome was. I thank you all in advance for taking your time to answer me.
