Ok so i have done taking letrozole to get me to ovulate. Well my period last month started may 6. Then went to the dr on may 18th and they did a ultrasound to see if i was ovulating. The dr said a good folic in each ovary. And to go home and have intercourse. And we did. On friday I spotted very very lightly till sunday. I took a test yesterday and it was negative. When should i retest or should not ?(learn more on Glow: https://glowing.com)
