Good morning ladies needs some advice!
So my AF was suppose to start on the 11th and that same day I had very light pinkish spotting but the next 2 days I had a light flow and today I'm spotting like I did the first day which is kinda weird cause it hasn't happened to and am TTC so idk if it's implantation bleeding or just a really weird AF what do you ladies think?
