Can’t do ivf if no period ??

Me and my husband decided to do IVF. I always get period every months. We went to the fertility doctor and all the tested came up good except my husband has low sperm motility. We want to do ivf soon because I will be 35 in November !! Unfortunately, this months I’m late for my period almost two weeks already. All the pregnancy tests were negative. I don’t have any symptoms. I’m so worried and I want to get pregnant so bad.🙁🙁🙁 I’m waiting for my period so I can do the saline sonogram rest....I feel like I can’t wait anymore 😞😞
