please help my anxiety a little

ok. so. about four or so weeks ago i had sex. used a condom. he came. put a new condom on and threw the old away and finished. he came again. then i got worried it leaked or some sperm got into the new condom. so i took plan b the next morning

six days later (right when <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> said i’d have my period) my period came. it was normal (so heavier)

ovulation was so heavy after that period i though i had a yeast infection but it died down once i was done ovulating.

i began noticing that my nipples were tender and i had to pee more (now i don’t pee as much and it’s normal.) but i drink a lot of water but i didn’t feel like i drank more than normally. also craving junk food but that could be just because i got into a junk food habit.

four to five week pregnancy symptoms began to show up but i feel like it’s cause i’m psyching myself out???

is it just plan b doing this or

i can’t take a pregnancy test cause i don’t have a car and my mom can’t know i had sex (i’m of age yes. but still under her roof) and all my friends are off in college so they can’t help. so testing is outta the question for a while

should i be worried?? 😢 period comes in 9 days wouldn’t plan b be done with it’s wrath of symptoms after 4 weeks? or does it mess up more than one cycle

UPDATE : on the price of plan b and how i got that but why i can’t get a test

no test because i have no way to the store unless my mom gets me a ride and she can’t find out. it’s not the price of why i can’t get it, it’s the fact i can’t get there (i live in the middle of the woods to so it’s kinda hard) i wasn’t near or at home when i got plan b, time changed and now i can’t get a test. my friend got me plan b but is now away at college so
