Confused

So I have taken multiple tests I had 3 faint positives just recently and I took 3 more today and those were negative....I've used ALL pink dye tests...I am having ALL the symptoms of being pregnant (I have 3 kids already) so I know the signs & symptoms of pregnancy... I'm so confused as to why the tests I took today were negative...

I'm seriously about ready to get a blood test done, husband says to wait to see if my period comes(due sunday) he was swearing that my period didn't come because we hadn't had hard rough sex (well we fixed that problem and had hard rough sex) which ALWAYS helps my period come...and still nothing at all!

Could anyone maybe give me some advice or something..... thanks!!

Please pray for baby dust this way, I want another baby so badly!!!
