Going for a blood test today, I’ve only ever been late one other time and that’s when I was pregnant with my son in 2018, anyone else have this happen? Ovulated on January 18 and had sex 4 times during my fertile window(unprotected) took 12 urine test over the next 3 weeks, all negative although I swear I saw a faint positive we’ve been trying to conceive since my husband got home from deployment in August
