Testing Advice

Is it possible to be pregnant and still get a negative test?

I missed my period in August so I’m now officially 2 weeks late. I did the First Response triple check test 3 days ago. I only did 2 out of 3 and the results were both negative. I didn’t do the 3rd just because I’m tired of seeing negatives. My breasts are a bit sore and they seem a tad bigger (that could just be in my head tho), I’m bloated, I’ve had very slight cramps here and there but nothing consistent, craving sweets for the past couple of days, and today I had a little nauseous spell but it was very slight. What do you ladies think? Have I just skipped my period for the month? Should I consult my dr.? My mind is just running wild and I need some advice. Side note: my period has never been this late before. I’ve always been a “regular”.
