So it's been just around a week since my fertility window and I've how do i put it done it every day just about well during that window space. The past 3 days I have had weird cramping and a slight pain in my pelvic area. I've been over tired and super bloated. I used the toilet this morning and there was no spotting then about 3 hours later I went again and I had light pink blood. It lasted maybe 15-20 mins and left. I'm not due for another almost two weeks for my ELF (evil lady friend). Should I test?
