so I had what I thought was ovulation spotting around the 11th-12th ( had intercourse in that time ) and then roughly 2 weeks ago I was having extremely sensitive nipples, nausea, sore lower back, hot flashes and was out of breath easily and then I took a test and it came back negative.. symptoms continued for a few days and I went to emerge to see if I had another problem and they took a test too and it was negative, couldn't find a problem with me and then 2 days ago I took a 3rd test and it was negative too. Someone said it could be delayed ovulation but with the spotting is that possible? I'm not sure what to think here has anyone else gone through this?
