Progesterone cream

Lori
Started taking over the counter progesterone cream after O this cycle because I've had two early miscarriages and I suspect low P. I'm 13 dpo today and testing negative. I'm one day late for af. Will af come while still using it? I've read I may have to stop taking It for af to come. I'm scared to do that with the slim chance I could be pregnant!!! :(
