Help pls. Worried

Lakieta

So I’m late by 5 days on my cycle. I tested by blood and urine but both came back negative. I had some spotting on the 8th and 9th that didn’t even go onto my panty liner. Then all of a sudden out the blue I get a cold more like a cough and fever with headache. I don’t know if I ovulated late or just going through the motions. But my cycle don’t even seem like it’s on its way. Me and my fiancé been ttc for months now
