Feeling off

Currently 9dpo and feeling absolutely horrible. I feel like every bit of energy and emotion has been sucked out of my body. The last 3 days I’ve been suuuuuuper irritable and then crying for no reason. About 3 days ago I started light cramping, and getting headaches and EVERYTHING made me mad. The day after I felt fine other than being upset and sad at the same time all day. Yesterday I had literally no energy, I cried bc a lady said she didn’t want a straw with her drink then cried bc a guy told me to have a lovely day. I haven’t felt like eating at all (nothing sounds good) then last night I craved garlic burgers but only from a restaurant and not a fast food place. I slept all yesterday and all last night. My boobs have been hurting soooooo bad and are super swollen and my lower back is killing me. This morning I woke up and just feel drained, no energy, no emotion. My boobs are still swollen and hurting and I keep getting quick jolt pains in my upper stomach and my head is pounding. I feel like I’m literally going insane because I feel horrible but I’m not sick. I’m not getting my hopes up at all and haven’t even tested until this morning (which was negative) has anyone else felt like this before being pregnant or not being pregnant. I just am looking for possible answers.
