What do I do?

Question. I am 9 days past when my period is due. I am extremely regular and am never late. If anything my period may come early. Husband and I are TTC baby #2, we have been trying for 7 months with a miscarriage 3 months ago. I have sore nipples and am super bloated and gassy, nausea in the early morning and late evening. No positive tests yet, but could I still be pregnant? My first son is almost three and I just don't remember my symptoms with him.
