So tmi but last night I went to the restroom and found some clear slime on underwear , it had some white stuff in it too .. Then this morning I had really bad back and stomach pains for like three minutes two times while at home . And on the way to church 30 minutes after that happened I felt like I was about to start my period ... You know them awful period cramps . But I feel better now . Only thing is , it's really hard to walk around because my pelvic bone hurts so bad ... Any of this happen to anyone close to having baby ?
