I don’t know what go do

Diamond

So i have 2 <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> apps. They both say i am late 1sats a week this one says 4 days late. I’ve taken 3 test and they were all negative. I’m not stressed nothing. Honestly at a happy point that i haven’t been in for so long. I stoped my birth control November 29th to try for baby #2. What do y’all think i should do??
