SOS. Pregnant or period? Anyone had this happen?

Rileigh • Labor and delivery RN, wife, stepmom.

I am 1-2 days late on my period (Glow says 2, Flo says 1). We have been TTC for 14 months now and this was my second month on clomid. My progestrone level this month on CD21 was 35! 🤞🏻 I took a pregnancy test 2 days before my period was supposed to start and got BFN. Today I have been having period like cramps & some light vaginal pain. My libido has been high the past 2 days. Since I'm 1-2 days late I took a test awhile ago (NOT FMU.) and got another BFN. Has anyone else experienced cramps like their period was coming once they were late and then got a BFP? I'm going to test again in the morning with FMU but I'm trying to hold onto hope that these may be early pregnancy cramps and the test was only negative because I took it so late in the day.
