Please help!

Hello ladies, so the last time I had Intercourse was back in June on my period and as well as May on my period. I am on the pill and have been on it since November and I made sure that my bf wore condoms and pulled out before he finished. I checked the condoms and they were fine with no leaks and i saw him finish outside of me too so I know he pulled out with the condom on in time. As well as I took a plan b in May and June (I know it was really irresponsible and not needed)

These past 2 days I have been so sleepy. I don’t know if it’s the season changing, or because last week there were several days I only slept 4 hours because of school bc work, or because my doctor just told me I was borderline anemic and I need to take iron supplements to help with that (and I haven’t taken it). I also went to my friends wedding and i had on a spaghetti strap dress on and it was cold bc it was outside so I could be catching a cold. I have had my period on time these past couple months since June and recently had it sept. 13-17. It was a little light when I started but seemed normal to me and had small blood clots in it as well. I have taken numerous pregnancy test and this one was the last one I took

This was 9 weeks after I had had sex and just wanted to make sure I wasn’t pregnant but now I feel super tired and it’s making me anxious. Could I still be pregnant or could it be another reason why I just feel so sleepy. Thank you!
