Ok here is my problem. I have never worked out ovulation dates. Period is usually between 28 and 33 days, so 33 days would be today, 28 would mean I am late. No sign of it at all. Me and my bf just been BD'ing, no calculations, just to see. My symptoms are below, what do you think? I just want to know because I keep getting BFN's, could there still be chances of a BFP next week or something? Sunday night - twinges in tummy Monday afternoon into the evening - Dizzyness, headaches, nausea and strange taste in mouth that wouldnt go. I can only describe as a rusty spoon, felt like I could be sick but wasnt. Also strange ache in very very lower back, cant describe. Went to bed early. Did a HPT, but BFN Tuesday I felt again a bit dizzy in afternoon. But as I got a BFN, I went out that night and had a few drinks with work xmas party. Wed morning - bit hungover, but did HPT, and BFN Wed pm - noticed my boobs look diff. The areola which is huge anyway looked red, even my bf noticed. I also noticed the blue veins are visible, like just standing there opposite mirror they strike out, never had this. Not sure, just really different looking. Also noticed stomach twinges again. Today - Same thing with boobs. No pain. I was hungry earlier but didnt eat for hours as just didnt fancy it, weird for me. Now - Feel slightly dizzy, back ache still What do you think?
