discouraged

So I have had a lot of symptoms of pregnancy and me and my bf have been trying for months. -Backstory both me and him are 20 and I do have thyroid issues graves and hasimotos diseases sadly- but we have still been kinda trying really we just have sex and him ejaculate inside me everyday and if it happens before I have my thyroid removed then awesome. At least he thinks that's how I'm playing it but really I have been hoping to get pregnant before getting my thyroid removed and had all the symptoms and because I'm impatient I took a test early and you guessed it I'm "Not pregnant" but my thyroid issues doesn't explain why Ive been throwing up lately, along with slight cramping, food cravings and not wanting to eat some of my favorite foods, super sore breast, frequent urination and fatigue. Mostly the throwing up some of those can be explained by my thyroid I suppose, but I haven't had a fever and I'm not sick because I never actually throw up and not for over a week straight. I don't know what to do or think. 😭
