No AF and BFN

Well, She was supposed to come on last Thursday and missing. Took two HPT and both BFN! Last month I got her on CD 34. But I thought I ovulated earlier this time. I had some cramping on CD 21-24. May be I ovulated later than I thought or the B-Complex I'm taking is making it late. Anyway I'll wait until Thursday and see. Weird thing was in the middle of last night, I felt something stuffy on my right side. Not sure what it is. Let's see what Thursday is going to bring.
