CD 41 white creamy cm negative test

Sophie
Hi ladies, 
I really just want to share my frustrations haha ttc for 9 months after a heartbreaking MC so I'm on cycle day 41 creamy cm mainly noticeable when I got to the toilet not in panties. Tender nipples feel like I have gained weight this month I didn't track o date properly felt like it was putting too much pressure on muself and my partner! I'm so confused very emotional have slight back ache but nothing major feel like I could be pregnant fed up of seeing so many BFN what do you guys think could I be preg when would you next test? My cycle is usually better 36-40 days 
Thanks for reading Sophie xx
