please help... i feel alone :(

i'm on the pill and i've been having such weird symptoms that i've never had before. i heard that stomach problems are early signs and i haven't been able to get a hold of this stomach bug. i woke up one morning and i couldn't move bc my stomach hurt so bad then it stopped. i take my pill in the mornings and i'm always so afraid of it just not working. i don't know what to do and i'm so scared 😥 my period isn't due for about 9 days and i'm nervous she won't show up. everyone says i'm fine but he did cum in me the second day of my new pack, but like i said, i've been on the pill for 8 years consistently. my breasts have also been changing and i was cramping.
