I was thinking i was pregnant.

I’ve been having pregnancy symptoms like crazy and if i was pregnant it would be 4 weeks and 5-6 days. But i took a pregnancy test 1/23/24 and it came back Negative I went to the doctor 1/24/24 and they ran to pregnancy test they both came back negative, but i’m still having symptoms and my stomach is tight in the lower part. I was told they was going to take blood to see if i was or not but they didn’t so now I genuinely don’t know what to do. This whole month i haven’t had a period and my last one was 12/2/23 through 12/8/23.
