okay I'm new here and me and my partner are try. I am really needing advice! I am 15 days late for af, Sunday 1st May after bm (babymaking) I went to the loo and wiped (tmi) there was a little spot of blood on the toilet paper but nothing more just a spot, I had pinkish discharge 1 or 2 days before and after Sunday had a little brown discharge and thought the witch was coming but nothing till now and remains that way, had a slight shooting pain in both breast after that and breasts changed a bit got more fuller and lifted, had bad dreams for 4 nights in a row and terrible headaches, I haven't been thinking about it much now but haven't felt anything apart from being so so tired and bad headache once in a while, so about a week ago I took two clear blue plus and negative I know you shouldn't look at tests after the specific time but next day there was a faint line it was blue so don't think it was evaporation line and same on the other I took, I decided to take another one and negative next day that one had no faint line though.... so sorry for the massive question but so stressed and need advice! did one yesterday first response and BFN, will do one tomorrow morning first urine but have no hope it will be positive, I also have a blood test next Wednesday so will be 20 days late may show up if preg, HELP please !!!:(
