Late period negative test

Jessica

I had sex on the day that I was supposed to be ovulating I’ve taken 2 pregnancy tests 6 dpo & 10dpo they both came out negative but I think the last test I took was invalid because the first time I peed on it nothing happened so I went ahead & peed a second time which resulted negative... I am now 4 days late & I’m usually never late... I really don’t wanna take another test tho :(( what do you girls think???
