2 weeks late not pregnant

So my husband and I had an iui done on December 20th (peak ovulation day for me) and AF was due on the 31st, I had been cramping, peeing a lot, super sensitive and plump boobs/nips, and exhausted since the 24th (I actually slept most of Christmas Day bc I felt like absolute trash) fast forward to the 4th when they had me get a hcg blood draw done that was negative. I also tested that morning and it was negative. Stillllll nooooo periodddd 😐😶 wtf. Last week I went to my ob bc my southern region was super swollen and itchy, she said I have BV most likely caused from his sperm ph is throwing mine off 😰😷 she prescribed me a medication and it’s gone at this point but I literally still have all these symptoms and no period and not pregnant. Whattt the fuck is going on with my body. We were supposed to go through with our first round of ivf in February but if this shit can’t straighten out I’ll lose it 😇
