Sperm analysis results back

& Dh is good to go!!!

Dr wants to start me on prometrium for possible luteal phase defect. Not 💯 what this is, but my lp is 15 days long!! Is this too long? Also, we bd every night. Not to have a baby, just bc were in the mood. She said to wait 3 days before O, do the day of first positive test, then skip a day, then do it again.

I have gotten preg all other times from dtd ONE time during my fw, so I think this could be our problem.

(Little background info: This is our 5th mo ttc. Dh ttc for 10+ yrs & never succeeded. I had 5 babies while not ttc, but my cycles have been shorter lately & I gained 40 lbs a year ago from high prolactin. It is back to normal now tho)
