Late with no luck

Cheryl • Ttc in Late 30s
So I guess I'm joining the league of 35 and trying to conceive .. have to laugh I was always buying pregnancy tests when I was younger fingers crossed it was negative and now i cross them every time for a positive . Husband and I have been together 13 years. Giving this app a try to track my period which is pretty regular but we can't seem to get pregnant . We know the equipment works since I did get pregnant back in January but lost it a week later. Counting my days I was due Nov 12 for AF. No flow 6 negative tests . So I don't know. Just so discouraging . I haven't been this late in years. Even in my most stressful year of my life this year with parents divorcing losing a dog losing my first pregnancy and moving I continued to be regular for AF. So guess I just wait for her to show her face. Baby dust to everyone out there.
