i had a normal period june 10,2010, my ovualtion was due between june 21- 26, i spotted for a day and half on june 23rd. i was due to start my period on july 8,2010, but it didnt come on july 19th i started spotting 1 day just when i wiped other 2 days a little on a pad but not much. i have some pregnancy symptoms, my breast are really sore and that usually doesn't happen and my lower back hurts more than ever. i have 4 children, never had any syptoms with them. i had a hernia with my last one 7 years ago and surgery for it 6 years ago will that do anthing. ive took home pregnancy test 2 before missed period they was negative but that happened with my other 4, but ive took 4 this week 2 was completed invalid, they other 2 had negative in result window when i took it out of packaged and assume they might be invalid so so u think i could be pregnant still i would be 6 weeks from period june 10th.
