Today marks cycle day 62. I've been having some brown (sometimes pink) bleeding when I wipe but not everytime. Bloated, gassy and crampy. My boobs feel normal tho. Took a test last Saturday but it was bfn. Should I run to a clinic?! My last AF was jan 13-20.
​Or is it normal to have some brown bleeding  without many other symptoms?? We really want a baby!
