Is it too late?

Jasmine • I was diagnosed with BC2 2yrs ago in june. I Recently just received my doctors "OK" to try for another baby. This may be a long journey for me and my husband. Wish us the best of luck.

Today around noon had some light spotting when I wiped. I thought perhaps it was my period since it's due this week. So I went ahead and took precaution. Well I get home around 4 and nothing at all showed. I haven't had any symptoms of af this week other than being cold (which oddly enough is a sign for me). Here it is 8pm and still nothing.

My question is, is it too late for implantation? Could anyone give me advice please😔
