Hi ladies,
I'm new to this group!
I've decided last month to not over think TTC. This is officially my 3rd month trying. My period is suppose to come on Feb 7th. I tested this morning (Glow recommended) and BFN. However, today, I started having tender breast (never have tender breast w. period) lower back pain, bloating & cramping. Also, I'm feeling very "wet" down there & it's very water CM
Has anyone had this symptoms before BFP
Also, anyone test 3 days before period & get BFN then get BFP?
