Just ovulating or maybe pregnant?

I’m trying not to get my hopes up, but my husband and I have been TTC for the last couple months now. For the last few days, I have had cramping (mostly left side), nausea, fatigue, back aches, and most recently been constipated (TMI I know lol). Based on this app, I am in my fertile window right now and my actual ovulation day is Thursday. We have done the BD every day for the last 2-3 day’s, with the exception of yesterday (Monday) and plan on BD tonight! I usually get nauseated during ovulation, but the other symptoms are new. The issue I’m having is my AF isn’t due for 2 weeks, so missing a period won’t happen until that point. Which also means I am stuck waiting almost a month before I can test...

My question is, are these symptoms purely ovulation symptoms or could they be something more? My husband has one child from a previous marriage and seems to think I am showing signs of pregnancy, (he apparently also had a dream one night after BD that I was pregnant lol). I feel the same way he does too, but am also starting to doubt it as to not be disappointed.

Any insights would be appreciated. This will be baby #1 for me, #2 for my husband.
