I think i was due to start period on sunday Jan. 20th (usually have 40-41 day cycles, miscarried in oct. and have only had one cycle since waiting for second). on thurs the 17th saw very faint positive on pregnancy test (not sure if i read it within time limit). following tests coming up negative. felt like i was going to start on sunday...didn't start. negative test on tuesday morning but then small spotting on tuesday afternoon...didn't start. now it is Wednesday and still haven't started. Pregnancy symptoms increasing instead of decreasing. Do you think there is any possibility i could be pregnant or that my period will just be off if it was a chemical pregnancy? When do you think my period will come? Am really holding onto my hope of a pregnancy. This would be my third miscarriage. Thankfully i have three little ones here to bring smiles to my face.
