Hi everyone. Feeling very down today as my body is playing tricks on me. On cycle 3 of trying to conceive. I always had 28 day cycles like clockwork but they seem to have been longer since ttc. Between 28 and 32 days the last 3 months. I’m using the Flo app to track. According to the app, I’m two days late. Of course have tested and had two BFNs which is so upsetting because my boobs are really sore and I’m absolutely shattered. I don’t usually get these as period symptoms, I do get pretty bad cramps which haven’t happened at all. No sign at all of AF arriving so I just feel so frustrated. 
I’m 31 and now worrying that there is something wrong with me with cycles becoming longer. If I was pregnant, I imagine it would have shown on the tests. 34 days since last AF. I did test positive for covid on New Year’s Eve, I’m wondering if this could make my period late. Has anyone had covid then a late period? I haven’t tracked ovulation as worried about pricey tests.
