would it be possible to be pregnant?

im quite anxious because i have been experiencing symptoms lately. i am on birth control and i take it at the same time everyday. i also had my period that lasted 5 days, and i could say it was a bit heavy as i could feel it gushing out during that time. it also stopped on day 5 when i had sex. i don’t use any other form of protection besides pills.

before my period, i had lower back pain and cramps. my pee started to smell like a chemical and a bit sweet ?

after my period, im a bit out of breath, dizzy, and nauseous, but i didn’t vomit. i just felt like my stomach was full of liquid and couldn’t eat because of that. my pee still smells the same and i still have cramps every now and then.

i know taking a test will solve it but i haven’t had the time to go and get one, and that my pregnancy anxiety is too much. i think that it’s also heightened because there was a time when i put my pills in my bag and covered the bag with a towel when i went to the beach. but my bag didn’t get hot and it was only for an hour or two. one of the blisters also had a small puncture for i think 2 days before i took it, but i still got my withdrawal bleed.

what do you guys think? i just need assurance T__T
