Thanx CODwidow....what's a brisket? 
I feel like a fraud being on your thread but I know I am pg. Just did the test & guess what, I got another negative 
Let me tell you why I believe I am.
1.Had unprotected sex 2 nights running then realised I would ovulate 2 or 3 days later(sex was on Sat/Sun nights).
2.Woke up in the night on both Tues/Wed with indegestion & both those days I had constant headaches. I only ever get a headache the day before AF.
3.Continued to get headaches for next week on & off.
4.Last Thursday, 9dpo,I began to get cramping pains like when you're about to get your AF.Carried on over a couple of days, on & off. I only get pains on the day of AF. The ONLY time this has happened for few days leading up to AF was when I was pg with my 2nd dc. ( Only just read that the pains are actually implanting pains. Is that right, & if so does it take a certain amount of days to get a positive?)
5.Have been light headed, hungry for snax,starting to get tired in day I think, though could be getting mixed up with light headedness. Finding it harder than usually to push my 2yr old dc in pushchair uphill, really noticing a difference, not just general unfit.
6.AF didn't show yesterday,CD34. Usually around this time.
7.Today have started with the funny taste in my mouth too.
So there you go. Opinions please. I can't really make my body do all that because I'd like to be pg can I? I know those dates work with falling pg as I have 2 boys & my 3rd child is a girl & my friend told me the best way to conceive a girl is to have lots of sex up to OV but to stop about 3 days before. Would be great if I had another girl 
Sorry for long post. Need to finish my cuppa quickly & wake my girlie to do the school run. Will look forward to putting my feet up tonight & coming back on here (waves goodbye)
