7 weeks since last period, negative pregnancy test. Is it still possible?

Yesterday it was 7 weeks and a day since my last period. This isn’t normal for me. I haven’t had a missed or late period for years besides when I actually was pregnant. Like I said, yesterday I took a pregnancy test, and it was definitely negative.

Last year, I didn’t go through with the pregnancy but had strong pregnancy symptoms by week 7 such as sore and sensitive nipples, a lot of nausea all day long, so much fatigue I couldn’t even walk downstairs without feeling like I was going to pass out, food aversions, and whatever else I can’t remember. This time, the symptoms I have that match early pregnancy are just stuff I dealt with even when I was getting my period, so I’m confused. I’m not regular to the exact day, but I usually never miss a period. I have another pregnancy test I’m planning on taking next week, but even then is it even possible to get a negative result at 7 weeks?

Also btw I’ve never done an at home pregnancy test before and was wondering if it was normal that as soon as I started peeing the negative line showed up. I used a Clearblue rapid test.
