Still negative but feeling all the symptoms

We’re on our first TTC journey. Just a little background my period is regular, and just last month we’ve decided to try to make our second baby (ovulation between Oct 30 to Nov 5). Anyways, I didn’t think so much of it since it’s our first try and we didn’t really prepare for it or anything. So around 1 week before my period which is supposedly Nov 18, I started to feel mild cramping on my left lower abdomen, breakouts on my jawline, chest and back, which is so rare to happen when I have my period. So I was thinking maybe it’s PMS. I told my self I’ll wait until I missed my period and test, BUT my symptoms just keeping adding. So I tested a day before my period and it was NEGATIVE. I told my self, you are going crazy and all the symptoms are just from me overthinking. Now, I am 9 days late, starting to feel tightening in my lower abdomen, breast pain, feel nauseous mostly at midnight and morning before and after I eat. I tested multiple times and still BFN. So, I feel so confused, but hopeful. The disappointment kinda sucks at times whenever I see that it is negative.
