Spotting

Anna • *Mummy of 3 baby angels ( first loss Aug 2018, second loss with twins Jan 2019) after IFV treatment; 2 chemical pregnancy. Waiting for my rainbow baby. 🤰😇🌈
Hi there! I am trying to concive for 4 months now (i know is not a long time but still feels like more). I had intercourse on the 19th and 20th and a few day ago i noticed pink/brown spotting! Glow sais that on the 20th i had 33% to get pregnant. Is this implatation bleeding or can be something else? Fingers crossed. Thanks. Baby dust to all of you!! Xx
