Anyone else’s symptoms come and go?

5w1d here.. last week I had lots of symptoms that made me feel pregnant like off and on nausea, excessive saliva, heavy feeling in uterus, frequent urination, and just this mental feeling of being pregnant etc. Now all I have left from last week is breast tenderness which has gotten worse, insomnia, and off and on cramps and lower back ache. I haven’t had any nausea in a couple days and I only have the heavy feeling in my uterus when I first wake up in the morning. My hunger is still there except it’s only at night now instead of all day. I don’t know I just feel like last week I felt so pregnant physically and mentally and now I don’t and it’s making me really nervous. I just had blood drawn today to check my levels so maybe that’s what’s bringing out all this anxiety. I just have such a bad gut feeling like I’m going to lose this baby and I know it’s a wait and see kind of thing, but god it’s so hard 😭
