So I did my Home insemination May 14/15 every test came back negative my period came 7 days late but it finally came but the weirdest thing is it was only on 4 days and I had super bad cramps....

My period has ALWAYS been 7 days and when I started this fertility pill it became 6 days and spotting on the 7th day (I’ve been on the pill for a year now) And I rarely have cramps but this time it was so bad I couldn’t get up (like I laid in bed for 4 days) once they stopped that’s when my period stopped.

Someone please tell me why........

Like is it because it’s the 1st time sperm has been in me like why such a dramatic change??
