I'm confused because I took two ovulation test yesterday "one in the morning and one at night" and the same today. I thought I was ovulating yesterday so I had sex then this morning I got curious and tested again and the line was way darker than yesterday but I haven't had time for sex today yet because I had to work and take care of kids so I have to wait until tonight. I tested this afternoon and the line was lighter so did I miss my chance for this month?
