TTC AFTER LILETTA

Savanah
I got LILETTA (IUD) removed January 16th, 2017. I had it for almost a full year. I have been TTC #2. I had my period right after from January 18th-22nd. I have been having horrible cramps as if I am going to start again, all my pregnancy test say negative😞 how long do you think it will take me to get pregnant since I was on BC? I hope not long😕
