I'm 5 days late on my period and my cervix is still high and slightly open on Monday 20th Jan 2025 I had the worst cramps, thinking I was coming on my period as I was due. My periods have been every 27 - 30 days for the past 2 years. I've been tired, not wanting to eat. Had lots of clear cm on 18th-20th Jan. I did a test this morning and there is a faint skinny line. Is that an evaporation line? Or a bfp? Thanks all
