My spouse & I have been trying to conceive. The last time we inseminated (in home) was Dec. 13th. She started her period on January 2nd (lasted 3-4 days), but hasn't had one since. She's always had irregular periods, cycles lasting up to 43 days max. Well now as of today shes on day 66. We took 3 home pregnancy tests & then went to the doctor & the got a blood test done.. all tests have came back negative. Our primary said that if she hasn't started in another 4weeks to make a follow up visit. Just any advice or feedback would be appreciated.
