Late period, 2 negative tests

[kellouise]

Hi everyone. My first post on here.
My periods are on time every month without fail.
Every 28 days I get my period usually. I'm now three days late and I know that's not a great deal but I tested with clear blue and got two negatives.
BUT I'm having symptoms such as weight gain, headaches, new cold, sore boobs, fatigue, and some food tasting weird.
Am I testing too early and could I actually be pregnant or am I just reading into things?
It's driving me crazy

I was one week late, had negative pregnancy tests for a week but it was my second period I was expecting after they returned due to breastfeeding, I'd obviously ovulated late as I got a positive pregnancy test 1 week after my missed period, so there is a possibility that you could be pregnant or you might not be, but if your tests are negative right now your not making hcg so the pregnancy hasn't implanted yet, or because you ovulated late your busy is a bit behind in shedding it lining, I'd get a first response test (pink dye) and test in a couple if days.
