And another

Well my husband and I have been actively TTC for four months now and I know that doesn’t seem like a super long time but I have endo and have had some horrible cysts so it just seems to be forever. I’m between 9 and 11 days late do I started to get excited, took a test last Friday and it was negative so thought I’d give it until Monday still no AF so I took another, negative. So I waited until today......called the doc even and she thinks it might have been the antibiotics I was on for strep last week but I built myself up to take another test. Took two different kinds today and

Negative. I’m beyond heartbroken, trying not to be but damnit this is hard, any suggestions?
