Hi, I'm on CD35 and have a 33 day cycle usually. DH and I dtd at all the right times according to opks. I have been experiencing left side pelvic pain and cramps for the last week or so so fully expected AF on Monday. She hasn't arrived as yet and I'm now very bloated, headachy and knackered. Did a test Monday and today, both BFN. Am I testing too early? Should I wait a few more days? Had a chemical in Nov so reluctant to test but eager to know!
