Missed period!

Hello, looking for some advise.

I’m 44 and hubby is 42. We’ve been through IVF six time, pregnant twice, one ectopic and the other baby heart beat stopped after 10 weeks! Four years ago we decided that it was best to stop trying with fertility drugs because not only it was stressful, it was also very costly!

Fast forward to this month, I was supposed to get my period May 6 (according to this APP), It would’ve been cycle day 31 (I’m usually getting my period on cycle day 27-29) today is cycle day 34 and no period! I’ve never missed my period! I totally forgot about my period this month because I’ve been busy with work until I looked at this APP and realized that I missed my period! Today I took a home pregnancy test and it was negative! Not sure if it was due to maybe not enough HCG. I remember when I was pregnant with my daughter, the doctor couldn’t tell until I was six weeks, this was twenty six years ago!

I’ve been extremely nauseous for almost two days, tired, sleepy, hips and abdomen aches on and off, I even touched my cervix and is extremely soft, high, closed and full of white creamy stuff...and my nipples are so perky and they hurt!

I’m not sure what to think, should I call my doctor for blood work or should I wait?? I’m sure all pregnancy are different!
