Today i am currently 16 DPO (af due at 14 DPO). Some on and off cramping since yesterday weird cramps not my usual af cramps. Sore bb's since yesterday also on the side. (Very weird for me). Creamy cm since 5 or 6 DPO. Cervix is almost unreachable and medium. i am never late and this completely threw me off. I tested today with FMU bfn. Any advice?
