hi,last month i missed my period.im taking the pill, i thought i might of missed it due to stress. but the rest of the month iv just been wanting to eat alot,i was pooping alot(sorry for tmi) but last 4 days or so iv just been really bloated and just abit sensitive to the touch next//above my hip.and slight lower back pains,not sure wether its due from sleeping bad or a bump.yestrday i had taken my last pill. and expecting my period, but im just weary as all i feel is slight cramp .bloatiness. the pack before the last one i had, im not so sure if i missed one or not and wasnt taking them at the right time. i worry myself too much, iv never missed a period, and hopefully not miss another. abit of advice please
