So I started my period on April 1st and ended on the 6th. According to glow my fertile window was between the 8th- 14th... My husband and I had sex on the very first day of my fertile window and the last 3 days of it.. And I've been having mild cramps and really bad headaches for about 2 days now but they aren't constant. Also accompanied by some slight nausea.. But I'm confused because idk if maybe my ovulation wasn't when glow suggested and maybe that could be where my symptoms are coming from or if maybe it was spot on and I'm having some early pregnancy symptoms or if it's all in my head and I have PMS symptoms. Also AF is due in seven days on 4/27. Can anyone else relate? What was your outcome? Is it too early to test if I am pregnant?
