Help :((( what’s going on??

Soooo ladies, I was supposed to be getting my period on Nov 10 and I started getting lower back cramps then too. However my period has not come yet and it is 6 days late! I took a test on Nov 12 and had a negative so I got that out of the way. My husband and I️ are TTC! However I have still been cramping a little in my lower back every now and then, gassy, back pain, headaches, and Sorry for the TMI but I’ve had some bubble gas or something coming from my V area! But no period still? I mean is it possible my period skips this month but I have all these things going on for no reason. Differently though this month is that my breasts do not hurt me like every month before I get my period. Just hasn’t hurt me at all which Im not sure if that means I didn’t ovulate or what the story is. I️ called my doctor and she said to test again and if it is negative she will give me something to bring my period. Is that a good idea or should I️ leave it alone? Has anyone experienced this? Any advice?
