Ladies help

London

I am having all the symptoms of pregnancy. Nausea, tired, headaches, dizzy, peeing frequently and hungry.. last month I had 4spotting days of light cycle with 2normal flow days which is not my normal 6days. It usually heavy 4days and spot last two. I keep getting light cramps on my lower side.. all test say negative. With my son urine test couldn’t detect till after 12 weeks. Should I just take blood test? Feb cycle doesn’t start till 26th.. any advice?

And keep fingers crossed cycle does not come🤞🏼
