Pregnancy symptoms after period ends???

Did anyone experience bad headaches, spotting, sore breasts, or slight cramping on the first month of their cycle after stopping birth control pills. I got my period Jan 31st (it ended Feb 4th) and this is my first month without my pills and I feel off. My head is killing me. And so are my boobs 😩 sore boobs isn't even a normal symptom when my period is coming. What could be causing all of these.,
