BFP Spotting then BFN

[Baby3PraiseBe]

I tested lastnight at 7pm, BFP on clear blue digi showing pregnant 1-2 weeks.
have nausea, veiny rings round nips, light cramping and can express colostrum (this was my first early sign).
cramping through the night and brown spotting this morning with a little bit of red, more brown that red and have taken another test, another CBD, the 2nd from the packet and it says Not Pregnant.

Not sure whether I am actually pregnant or not?
I can test again but wondering if blood in the urine can screw with the result?

any advice?

It's hard to say, I'd guess you're only just pregnant, and it may be that it's still difficult to detect. I think only time will tell. No the blood wouldn't affect the result. Also you can get false negatives, but not false positives. Brown blood is old blood, and you can get this from implantation bleeding - good luck

Thanks so much for your reply. I’m in the toilet every half an hour checking the situation out! This baby wasn’t planned and haven’t shared with a soul yet. Hoping the spotting stops and I can test again tomorrow. Still got all the symptoms plus absolute fear of a chemical.
