Confused and think I'm pregnant sorry If tmi

So me and my boyfriend had sex on a couple days on my fertile days and on peak of ovulation. Had some cramps a day after ovulation and now. I'm about 10dpo? I ovulated on the 19th. I haven't checked my dpo today im about 10 or 11. I have been extremely exhausted that last few days I have been taking some naps. I never take naps. My period is due oct. 3rd. Cigs have been making me little headed the last day or two every time I smoke one. And that never happens I've been smoking since I was 15. I have been very emotional and very very moody . Was arguing with my boyfriend all day the other day and we barley argue. Just that day I was just very moody and he even noticed it and asked if anything was bothering me. Been feeling like I was gonna start my period all week not like hard feeling but little feeling. This morning I woke up at 6. Had to bring my sisters dogs back in I just went pee and there was VERY light streak on my toilet paper when I wiped. I put a pad and thinking it was my period and i didn't get pregnant but I woke up a few hours later and i felt something come out like when I am bleeding so I thought I was bleeding and had to change my pad I went to the bathroom and nothing. My pad was CLEAN 100%. And I wiped and there was NO blood not even the light streak. It's night time now and I'm still not bleeding. I shouldn't anyways since my period isn't due till the 3rd. I now feel Nausea more like stuck in my throat kind. And little in my stomach. Boobs are kinda sore but not that much. Very tired also. Could this still mean I'm pregnant? I didn't know when to test and kinda wanted to wait till the 3rd when Period is due.
