Lower abdomen pain sneeze

Been TTC for 3 cycles now, and looking at the past 3 months I should be spotting or AF starting today.

I got a BFN this morning

But I’ve been sneezing a lot lately, and when it happens I feel a twinge or a pull where my ovaries might be, my lower stomach anyways.

I’ve been seeing other threads of this being round ligament pain, but only confirmed by BFP and pregnant women at least 4 weeks.

Is there possibility I might be pregnant ?

I’m throwing a birthday party and the negative result makes me think it’s okay to have a few drinks but I’m nervous about that as well if there is still hope
