I'm 4 days late for my period. I didn't track or test this cycle, but based on how long my cycles normally are, I'm 4 days late. I had sex on 15th May and on 30th May, with ovulation predicted on the 19th May. As my app reminded me I'm late, I tested. I got a vvvvvf line. This is what happened last time and it was chemical. Vvvvvf late lines that progressed slowly and then nothing. Feel so bummed out. TTC for a year now! Anyone else have multiple chemicals?
