Withdrawal symptoms from contraceptive pill

[inkgirl]

I came off the progesterone only pill 3 weeks ago roughly. Ive had all sorts of symptoms, very similar to pregnancy symptoms. Not pregnant as of yet as pregnancy test are negative. It makes me worry if I'm this sick now how sick am I going to be if/when I do fall pregnant.
I got sicker and sicker with each pregnancy and got told it will only get worse each pregnancy i have. This will be the last. I plan on getting sterilised after having my next one.
Did anyone else get withdrawal from the contraceptive pill? I didn't the first time I came off. This time is awful so many symptoms

I don't think withdrawal from progesterone is a thing? Could it be another illness that happened coincidentally at the same time?

I didnt think it was either until I looked it up. Dont think its an illness as its been going on a little while now
