Ok so today I'm 3 days late and tested negative just now but this morning got a faint again. And yesterday st 2 days late got a faint again. What's going on? Could it really be that I'm still early on according to my calendar I should be 4 weeks 2 days so is it possible it just won't show up positive on the test yet? I'm 100% I ovulated because I took an OPK and got a positive on March 29. So if I ovulated wouldn't that def mean I would be getting my period? I've been regular with my period till now. Has anyone experienced something like this that can help me. I have no signs at all of AF. I have a swore left boob on the bottom and nausea here and there and I'm tired.
