Have tender , missed period & slight cramping?

Can someone please advice. I've had tender for almost 2 weeks now, I do normally have this felling but not for so long before I start my monthly cycle. I've had on & off cramping, similar to period pain. I am 2 days late now, but still wanting to wait another day or so before I do a HP test. Has anyone else had similar symptons & known that they pregnant... We've been trying & have had no luck, so really want to wait before we dissapointed again..... We were thinking to rather let my body takes its own course & see what happens, but its just so weird to have these feelings & symptons which i havnt had before.
