Pregnancy signs while bf

I feel like the chances I can find someone who has been in my exact situation will be hard.. but here it is. Im still breastfeeding my 18 month old. He eats 3 meals a day but still nurses enough to keep my period away. I haven't had a period since giving birth. I take tests monthly. Im waiting on tests to ship to me and Im freaking out in the mean time. My boobs have been burning, they feel like they are on fire sometimes. Ive had mastitis twice and its not that. It just happened out of the blue. Now Im thinking man Ive been super hungry and thirsty lately, even hubby commented on how much ive been eating lately. Ive been cranky and tired and getting mad headaches daily for 2 weeks. Is this weird burning sensation a symptom of pregnancy? Ahh. Im probably freaking out over nothing. Thanks for listening to me vent 😂
