D&K`s

Okay ladies , so the day before yesterday it was around 11pm I ate some banana pudding ( p.s me and hubby has been trying this month ) but anyways I ate then I went to go lay down my stomach started hurting so I was like hm maybe it's gas but before all of that I've got pms symptoms if it is pms idk but I have sore tender breast to the point my husband can't even touch them which usually they don't hurt as bad when I come on , I have lower cramps I recently been feeling some pain in my right side , back pain , I've been eating alot too as well like I just been so hungry lately . I was late last month too ( me and hubby was trying to ) my period was due on the 26th of this month I still haven't had it so I'm 4 days late today. But back to the night I ate banana pudding 😂 so I'm like hmm maybe it's gas so I didn't pay it no mind then my stomach started hurting worse to the point I started getting hot flashes and feeling like I had to throw up so I took tums it helped a lil bit but all night that night I've felt so sick woke up yesterday morning at 7 feeling like I had to throw up but i just had to burp 💁 so I went to go back to sleep I woke up feeling so weak and sick like I didn't feel like throwing up anymore but my back was hurting so bad , I had a headache , my stomach didn't hurt as bad but it felt like my stomach was sore wasn't hungry at all I didn't even want to eat so I didn't eat all day that day until my husband made me eat some toast I felt so drained and weak y'all like I never feel like this before . Today I woke up feeling a little better but I could tell something was still wrong I felt so tired and weak we went to the store in the store I started getting hot flashes again and feeling so weak and sick kinda nauseous but not really so we came home I ate some soup and crackers dranked ginger ale then I felt so tired so I went to sleep I just woke up and I'm still feeling weak and sleepy I just ate again too as well . Still feel drained right now but a little better . No one in the house is sick , I've haven't been outside either . I have no fever , no vommiting, no cough , stuffy nose a little bit , no diarrhea, no sore throat what could this be???? Should I wait to test if I'm pregnant ?? Has anyone felt this before??
