help please!!

Ladies I would love to have your input and thoughts! My Mirena fell out on April 6th (ouch by the way) and went on the mini pill ( quite poorly.. I would always forget to take them and missed a few days here and there) til about May 10. (DH and I still weren't 100% on TTC #3. We became confident that we were ready.. So as of May 13th I stopped bc and we began the concieving journey. I had my "period" April 21-29. Now nothing. it's 40 days since my last period and I've had all the pregnancy symptoms for about 2 weeks now. ( queasy tummy..cramps on and off..heartburn all the freaking time..food adversion.. frequent peeing!) I took 3 tests all negative. Just not really sure what's going on... any thoughts would be appreciated!!! 😁
