Ok, I’m 29 but basically 30.....TTC#1

Hello, I need some advice....

I am very frustrated right now. Since September, I had normal cycles due to some weight loss before my wedding, I’m assuming. I’ve gained a bit back, not that much (fluctuates around 10 lbs due to some holiday tom foolery) and now my period is 5 days late. I don’t really have any symptoms of AF coming OR pregnancy, although I was having increased EWCM a few days ago to the point I though AF was coming. I was also nauseous for about 1 week to the point of vomiting one time one week ago, but that has passed.

Do you think I could possibly be pregnant or are old patterns coming back to haunt me because my weight is fluctuating? I’ve had to step away from the HPTs because I was driving myself crazy with the BFNs. I was going to try and wait until I was one week late to test again.

Any advice is welcome. Thank you ❤️🥺
