I am 10 DPO today and have had zero symptoms except very sore nipples for past 4 days and extreme,debilitating fatigue yesterday at 9 DPO (by fatigue I mean i had to cancel a scheduled teaching session ten minutes before it was due to begin, ask students to leave, buy fresh tickets and take train home in a daze).
I just did a 10 ml internet cheapie. Within five minutes I,e. It was still wet, a thick but fuzzy pink line appeared lower in the stick - I.e. It was not dark like control line but it was pink, not white/clear, it was parallel to control line and lower into the stick as it should be. I know I am not imagining this, it's never happened before and it wasn't a squinter. I didn't even have glasses on and this was pinkness personified!
But here's the thing. I then rushed downstairs to find my phone to take a pic and in front of my eyes it vanished. Then of course the stick dried.
I know I need to retest at 11, 12 and so on DPO. But could I be pregnant? we had sex CD 8, 10, 12, 13 am, 13 pm, 14 and 15 for an LH surge on CD13 and ovulation on CD15.
