Help 😩

My period is 10 days late and I’ve had 2 negative pregnancy tests (day 2 and day 6). It’s been 43 days since the first day of my last period. I don’t really know what to do at this point.

I stopped BC the end of January. I was on BC pills for 7 years and had an IUD for the previous 5 years.

My previous cycle was a total of 35 days. Currently I am not testing temperature or ovulation.
