Wondering

So according to this app I am almost to a week after my period was supposed to come and nothing, my boobs are a little sore and I had a night of cramps a week or 2 back. We just got married and started ttc so I have taken 3 tests and gotten negatives. My period has been pretty much spot on with this app except for last month. It is starting to make me concerned something is wrong with either me or him, I'm just confused and not sure what I should do or feel at the moment. I feel like I have had some pregnancy symptoms but now not sure if thats just me wanting a child so bad that I "pay more attention" to stuff that's always there with my body. I want a child so badly its depressing when it doesnt happen. Thanks in advance for any advice or support! 💙
