Fingers crossed!

AF has been very irregular since I stopped my bc last year. Doctor wasn't concerned by the craziness- just thinks it's stress related. Not 100% sure when AF is expected but I think sometime in the next week and this morning when I went to the bathroom there was some spotting. I'm praying its implantation bleeding and that this month we will finally get a BFP! We've been trying for 13 months now and I'm just tired of BFNs!
