Feeling confused, do you see it?

My husband and I have been trying for 2 and a half years to get pregnant. I have PCOS and this last month did the highest dose of Clomid. I have never been late on a period. My problem is I normally have too many periods. So last night we got these tests and I took the top one. We checked it promptly and both noticed the plus sign! We were so excited but also not wanting to get overly excited if we were making it up. So this morning I took the digital and it said Not Pregnant. Has anyone every had this happen? 10 days late today.

I'm going to make a doctors appointment as I've been having many pregnancy symptoms. Maybe they can help iron this out for us.
