Very frustrated

I’m technically 3 days late on my period but every test I take (first response, clear blue, and the cheapies from Walmart) all come back negative. My husband says not to stress in case I am pregnant and the hcg level isn’t high enough. I just wish I would get my BFP. Been TTC for 2.5 years now with no luck. Once I’m a week late I’ll schedule with my doctor for blood work. Been trying to do research online but not really seeing anything of use.

Anyone else have this happen and end up being pregnant or not?

Thanks 😢
