Ttc going on year 2

Lea
When we first started trying we just went with the flow after a year we found out my husband had a varicocele and his sperm count was only 13 million which is really low. He had surgery to correct it in July and I honestly don't think it worked but he has to go back for another sperm analysis they schedule them after he should be completely healed. Anyways six months since the surgery and still no baby. Since the one year of ttc iv been monitoring my ovulation and keeping track of my cycle length. It use to be anywhere from 28-32 days and 8days of bleeding. Now for the last few months it's been 30-36 the last two months 36 day cycle length and ovulating on day 30 and bleed for 4 days. I'm so frustrated I just feel like the odds are against us no matter what. I can't even be happy for people how find out they are pregnant because I want to start our family more than anything it breaks my heart
