Should I test???

Ok so this may be silly but Idk if I should take another preg test. I took one on 9/23 and it was negative( that was 11DPO) and then I started bleeding the next day. I assumed it was an early period. Early by about a week. I usually have super heavy bleeding for the first 2 days( I'm talking a super tampon every 3 hours) and cycles normally last 5 days. This cycle I didn't bleed as heavy- I only used a super tampon first day and they lasted 6-8 hours. And then I only bled 3 days instead of 5-6. Second 2 days were pretty light( regular tampon every 8 and it wasn't full)

So today marks my fertile window- and I'm EXHAUSTED. Im usually very much a night owl and stay up until 11-12 or later and I'm up at 630am for work. Well.... last night I fell asleep on the couch at 9pm! And slept all night! I've been so tired all day and just dozed off for a second at work.

Many chance I could be preg?? Should I test??
