1 day late BFN

Me and my bf are trying to conceive baby number 3. My period was January 27th- February 2nd. We had sex the next day and every other day while I was fertile. Af was due today I am never late usually my period would come in the afternoon but now its almost 7pm :( Took a pregnancy test and got a BFN am I testing to early? I was having slight cramps this morning. I am having back pain and I feel super overwhelmed and tired. My boobs arent sore, but BF said they look a little bigger UPDATE woke up did another pregnancy test and still negative :(

Second update its currently 7 pm no cramps just super emotional and tired hoping AF stays away fingers crossed
