curiuos and confused

Hindi po ko umiinom ng kahit anong contraceptive pills, after i gave birth to my first child nahirapan nko mabuntis..my last sex was February 7 then i had my period february 15 saglit lng as in two days then yung period ko dry then after i feel cramps tpos masakit minsan ung balakang ko sa kanan then nagkaroon ulit ko mg period last March 16 then two days ulit at dry at ung tiyan ko minsan malaki siya sa paningin ko lalo kpag nagsusuot ko ng fit na dress. Hindi ko nagkakaroon ng malaking tiyan kze mabilis ang metabolism ko kaya hindi ko bloated then this morning masakit ung kanang tagiliran ko pagkagising ko..just curious lang if this feeling is normal..
