NSFW 26f blood after peeing

I’m posting here because I won’t have health insurance until February. I will be doing a urine culture tomorrow because it’s all I can afford. Just looking for some peace of mind right now.

I’ve had some blood after peeing (between periods) on and off since the end of October. It usually clusters, where I’ll have it 5-8 times in one week and then it goes away for a few weeks to a month. It presents after I've urinated, and is there when I wipe. I haven’t noticed any spotting in my underwear.

There is no pain while urinating. l took the prescribed dose of cephalexin (2/day for 10 days) as a precaution and noticed no change, so I’m highly doubtful it’s a UTI.

Around the same time this started, I started to experience pain during and after sex. This occurs about half of the time I have intercourse now. I can't help but think these symptoms are related as I've been having sex regularly for 8+ years and never felt this pain until right around when the bleeding started.

Other symptoms include: frequent and powerful urge to urinate, constipation, bloating (not unusual for me because I also have celiac disease)

Medical issues within my immediate family: -lupus (potentially inherited because I often have a textbook a malar rash and random bruising/low platelet count, but I haven’t sought a formal diagnosis) -kidney stones -diverticulitis -Sjorgen’s syndrome -Hemochromatosis -Hashimoto’s disease (have had my thyroid tested twice and had no abnormal results)

I’ve done a lot of research, but can’t tell if this is endometriosis, fibroids/polyps, or something more serious. Looking for any insight. Thank you.
