Opinions please!!

So the first day of my last period was Feb. 19th. I was supposed to start my next period Mar. 22nd but I’m about 16 days late currently, I’m assuming I’m pregnant since we’re TTC but I’ve taken two tests that were negative. I’ve just woken up to use the bathroom and I had a small amount of very light pink spotting and I’m having some twinges of cramps kind of rotating between the left and right side of my uterus and a little in my lower back. I’ve been nauseous and had a more sensitive sense of smell lately. I’ve also been very weepy at the silliest of things.

I should just wait another week and test again right? I’m just dying to know. I feel like I should’ve tested positive already more than two weeks of no period. I don’t know. I can’t get a blood test here without a positive urine test. TIA 💕ttc
