7dpo I believe...new to tracking ovulation...I always depend on my app to know when everything should happen lol..wanna wait to test til after the 19th...I've been hella fatigued lately & my stomach seems to be stuck on permanent bloat (I'm so slim normally ugh) two days ago I had baaaaad cramping..only lasted from midday to throughout the night..woke up to no cramps since..could that one day have been implantation? Never had the implantation blood w/ any of my kids...I can never get a BFP until at least 7wks or at least w/ my other three I didn't get a positive read til 7+ weeks...hesitant to test at all...really might just wait & see what happens w/ AF...
