Hey Beccaface. I only read your posted so what I'm about to say might be covered/said by one of the other ladies. Could the problem be because your trying so hard? We all know how much it sucks to walk by 17 year old girls and see them pushing baby carriages. Or a family with 4 or 5 kids. I think, actually I believe that your trying too hard, and we all know that if we push something it'll only take longer. Let nature take it's course. Stop charting, stop obsessing (even though I know it's hard) and just let things go with the flow and tell yourself "if it happens, it happens" and I'm sure next month we will all be congratulating you on your BFP. I actually had a girlfriend tell me today that I'm looking into things too much, and I stopped and thought to myself "wow she's right". She even said the more you drive yourself crazy the more stress you'll put on the baby if in fact your pregnant. That's why I'm trying to help other women on her instead of googling and search my own symptoms.
I wish you and your partner all the best, and I promise you it will happen but you just have to relax. FX
