It is now 10 weeks since my last AF, and I thought I had a lot of good pregnancy symptoms - ovulated at right time, what I thought might be implantation bleeding at right time, etc, etc. Took a test around 7 weeks after last AF, as I have rather irregular periods but should have had one by then, but got a BFN. Very upset - have had lots of early MCs and had almost given up. Since then I've been trying not to think about it too much, but over the last few days I've been feeling more and more nauseous for no particular reason, I keep getting really bad headaches (which I've had for the last few weeks), my breasts still hurt. Does anyone think its worth doing another test?
