Pregnant? (Repost because I'm desperate lmao)

Crow

First things first please don't post rude comments. My question may be "dumb", but please take into consideration that it comes from a place of paranoia and fear however and rightly so given my circumstances. I've thoroughly educated myself on sexual health, and I understand the chances of me being pregnant are low. There's however still a chance, though very very slim, and I'm concerned I may have had some serious bad luck.

About 2-4 weeks ago (I don't really remember) my boyfriend and I had sex. He wore a condom and I have a Mirena IUD, I thought it would be safe and we wouldn't have to worry about pregnancy especially because I pretty much lost my period due to the IUD, eating disorder issues, and a few other things I'd rather not mention. Even without the IUD I thought I'd be infertile (I got it because I was having cramps so bad I'd vomit constantly, pass out from pain, and I was also extremely anemic). The condom had no breaks or tears to our knowledge and my IUD is properly in place. All of that being said my period came back about 5 days ago, but it's very light. I'm worried it's implantation bleeding as I'm having a lot of early pregnancy symptoms. I'm not sure if it's just my body being really fucking weird all of a sudden or if I could be pregnant (literally the last time I had a """period""" was when I got my IUD and bled for 2 months straight because of it and that was almost a year ago. I haven't had an actual period since mid 2020 probably). I'm having waves of extreme appetite loss and nausea and then waves of extreme hunger, I also suddenly and coincidentally fell into a really deep depressive episode right before this all began. I'm having cramps on occasion, constipation, and extreme fatigue. Some of these were regular period symptoms for me, but the constipation wasn't, nor this level of depression. I'd get moody and my depression and anxiety symptoms would worsen, but this currently is beyond unbearable.

I can't ask my mom for a pregnancy test as she doesn't know I'm sexually active (and there's good reason for that), I'm scared to ask my boyfriend because I don't want to worry him, and I could potentially ask my friends to help me out but I'm anxious to do so. I don't have any money I could use for one at the moment so it'd have to be purchased by someone else.

I'm gonna state again, I know a lot of this probably sounds stupid. I've been called dumb and immature on here multiple times on here for my questions and concerns. I'm fairly young, but that doesn't mean I'm an idiot. A lot of my paranoia likely comes from mental health issues as well as a trauma response, and I'm consciously aware of this fact, but it's still hard to rationalize it all on my own. I simply want input and to hear someone's voice outside of my own on the situation. Please, I ask again, keep it kind. You can be blunt (which is actually very welcomed), just don't be rude please 🥲

Anyway, 10 page ramble over, does anyone have any advice of any kind? Am I overthinking things, or could I actually be pregnant? If there is a possibility does anyone have any pregnancy test recommendations? Preferably cheap but still accurate if possible. Any input in general on this topic would be great. Thank you so much loves
