Silly question probably..

Side effects of going on and getting off the pill frequently?? I stopped taking my pill maybe a month and a half ago because i didn’t like how it made me feel, but had a bit of a pregnancy scare so husband and i talked and figured it be better to just be careful and take the pill. So I’ll order it again tomorrow. But i also stopped taking it around Jan/Feb, started again end of Feb, stopped in end of March. Will i get fucked up? Lol. I feel illy asking this, I’m 24 and already have a baby, i should know but i don’t 😕

Also I’m supposed to start my period any day, technically today but nothing, took a test and it was negative. If i ordered the pill should i wait for my period to come before i take it or take it right away?
