Infertility 8 months

Gem

After having 3 boys without even trying, having ultrasound and bloodtests coming out all well im just getting more upset each month when my period comes bang on time without fail and not knowing why its not happening. I know people have tried longer im just upset after coming on aunt flo again today. Im now under counselling because its actually got to me that much. Just venting and fustrated . I cant talk to many because they either think im mad for a 4th or say oh well you have 3. The other issue is my husband is reluctant to go to the doctors, he isnt as emotional as me but hates the doctors and is grateful for the 3 we have. Has anyone else been through simular experience and offer hope or any tips? Ive followed my cycle too so that hasnt worked. Even tried a sperm cup after sex to insert to help keep the good there.
