So confused and Heartbroken

So I took a a digital test on Sunday (8/6) which came back with a BFP! I was shocked and excited!

Then yesterday I decided to take another test just because some of my symptoms have subsided. I didn't take the test correctly and it came back "Not Pregnant". This is from the same package as the first with I happened to buy on Sunday.

Anyway I wasn't completely upset but took another test this morning. It was Clearblue Plus. It was a BFN. 😱

My symptoms are so messed up. Not only do I feel pregnant still (not my first time), but I don't feel like AF is on the way. I'm extremely emotional, mild cramping, no spotting, slight occasional nausea, and mild fatigue. Also my cervix is soft and high with little creamy/sticky mucus.

My cycles are unpredictable but usually average at 39days which makes knowing when AF might arrive more difficult.

Has anyone else experienced this and still been pregnant??

Btw, I'm scheduled to see my doctor on 8/15
