Hi, I am 25 years old and I took my last pill on the 12th April and I had my withdrawal bleed 17th-21st. I had some thick clear CM on the 6th and 7th May so I am assuming I ovulated around this time which would make me 13-14dpo however still no sign of my period. Is this normal? I took a pregnancy test yesterday and it came back negative so I am not sure what is going on! Any advice would be great! Thanks
