I’m late ⏰ ??!!!

So I have two calendars that I have been using. One on eve and one on Glow. The eve calendar is what I have been using since forever and it has my periods on a 28 day cycle. I started using Glow after I got off my birth control in March to try to get pregnant. Glow has my periods starting a week earlier than eve due to all the craziness of coming off the Nuvaring. I started taking beef liver vitamins and conception the last month. All last week per glow I should have had my period but nothing. Just the cramp and twinges. No other real symptoms. I was expecting my SO to knock it on this weekend as usual but nothing. I got one small spot of blood on Saturday but nothing else. Today is my start date for my period for eve and no period. I tested last night bc I feel pregnant but negative hpt. I think I might have tested too early. Any thoughts?? My other symptoms are so light idk what to think. I want to know what’s going on with my body!
