Crystal • Ectopic 2015 >5 rounds IVF>one beautiful baby boy>one on the way
Soooo I'm new at this whole testing my cervix stuff..... I have no idea what I'm looking for well feeling for.... What I think I'm feeling seems hard. My husband and I just went through an ectopic pregnancy in and a corrective surgery in Jan. This time were actually trying so I just need insight on where and what I should actually be feeling for
