Nervous first time mom here

I’m 4 weeks and a few days and I’m nervous because I have been cramping a lot but I know to some extent that’s normal I’m just worried. I called my doctor and have an appt in 4 weeks. I’m just nervous until then. I haven’t had any bleeding just cramping. Today was suppose to be my missed period. So maybe my body is confused because I didn’t have a period obviously. My test are still dark. I had a little bit of a dye stealer a few days ago but the dye has been weird on my test since then. I have more test coming in tomorrow. Any advice. I know stressing is bad. I also have a low pain tolerance so even mild cramping feels like I’m dying. Also is it normal to bloat so much because I can’t button my pants anymore 😂
