Early Pregnancy Loss or Implantation Bleeding? *mention of abortion

So I first had sex with my boyfriend about a month ago. We did it at least once every week with I think the last time being around the 4th of this month. Almost every time was unprotected and he pulled out (even though we both think he pulled out in time, we had sex multiple times so I'm sure sperm could've gotten in me, but we both know pulling out isn't reliable). At first I started to get acne like bumps all over, which i shrugged off, but it was on my lower arms which is very very rare and there was quite a bit. Then my breasts started getting sore and even grew a bit, they still are pretty sore. I had a few alcoholic drinks during this time. I had some cramping, but last night it ramped up and I had some bleeding. I've had some intense cramps and bloating, and regular bleeding since last night.

I'm meant to get my period tomorrow, and i rarelt ever start early. I haven't been able to purchase a pregnancy test since i live with my family and have no car, and i figured it would be too early any way to detect. I feel the bleeding rn is not the heaviest, but it isnt light spotting.

Is it possible this bleeding could be from a pregnancy loss or is this bleeding regular for early pregnancy? Should i just wait until after this week and take a pregnancy test? Is it possible to get a false negative/positive? I don't want to wait too long because me and my boyfriend both agreed we don't want a kid and would get an abortion if something happened before i could get on birth control. So waiting might just make an abortion cost more as the pregnancy develops and we both don't have much money.

I know that abortion is not a form of birth control. I know pulling out isn't reliable. I know that me and my boyfriend were impulsive, we talked about it and used condoms the last few times. I've made appointments at PP for birth control but they were cancelled due to them being understaffed. I have made my decisions and I'm not looking to be told I'm an idiot. I know other people want pregnancy and can't and im sorry about that, but I'm talking about myself here. I don't want a child, i cannot afford a child, and i cannot carry a child to full term, i know i should've been smarter but I wasn't. Im just trying to figure out my current situation. I dont use the community section of this app often so I don't know where to post to avoid hurting peoples feelings. I just need some help.
