I'm in the same exact position as you. My period was around the same time in January and I didn't get it in February. I tested a couple days after my missed period and it came out negative with blood and urine tests. The doctor said that sometimes it can still be too early to detect in some people at that time so I am waiting another week! Just my advice, don't test too soon or you may get a false negative. Good luck!
thanks for the advice mamofonetrying42
I would retest this weekend. Good Luck :o)
