Dearest Machair, your sweet words are so touching... First, I'm so sorry about your Dad! And you're right, my Dad's cancers have really changed my life,now everything scares me, every little sign of illness in myself, my mom, my husband, even my cat! makes me think about the worst things. You also have to consider that my husband too has been an oncological patient. He had acute leukemia just 8 months after our wedding (thank God he's ok, he won his battle against this monster, that unfortunately stole our chances to have children... you all are friends of mine and I feel free to vent!).
Back to my problem, yes, I have thought about ovulation (I've hade pain in the right side of my belly and lymph node in the groin, as sometimes happens to me during ovulation). Today I've had less spotting and the colour of blood is brown now. In any case I want to see my GP, maybe asking her if I can do blood test to check my hormone levels. Can it be a good idea?
I thank you again for your wise suggestions and for your words of encouragement. I really feel they come from your heart and, thanks to you and all the ones who have read and/or answered my post, I feel no more alone.
Hugs to all, Lili
