Had sex last night and haven't started my period yet so took a pregnancy test was negative this morning :( then just a little bit ago went pee and wiped and the toilet paper had pink on it hopefully it's implantation bleeding and not my actual period! I haven't had a period or spotting yet since getting the meriana removed in January on the 26th!! please please keep me in your prayers and send baby dust!
