Negative test? But feeling pregnant

Hi everyone!

I’ve had unsafe sex several times recently, even on my most fertile days. I did pull out, of course. Naturally, it was still very welcome. Now I’ve been experiencing pregnancy symptoms for 2 or 3 weeks: nausea waves, occasional menstrual cramps, and sore breasts. I could only eat ice. I hadn’t really thought about it until a friend asked me, and by then I was already 5 days late. Eventually, I bled for 2 days (dark red) and then nothing for days after. I suddenly became sure I was pregnant, it was just this feeling. Then the test was negative? I have to say I saw a little blood (I think it was a scratch because it was just a wipe), I don’t know if that could have had an effect. But it’s completely negative. I’ve had hospital visits for years until 8 months ago because I bled too much and for too long. I now always have a period lasting 10 days, and a few months ago it lasted for WEEKS. So it surprises me enormously that this period is different....

What do you think? Let it go or not? By the way, these nausea waves are driving me crazy. I’m quite sensitive.
