Ok, I need some help here ladies

I am 7dpo today and around midnight last night I woke up, felt very nauseaus, went to the bathroom and proceeded to throw up!

I've been feeling a little off these last few days, so it wasn't a one off thing, although the first time I've actually thrown up and I'm pretty sure I don't have a bug either.

I've had a few other symptoms too, which include a very sharp, stabbing pain in my left side around my ovary a few days ago ( I had this last time I was pregnant too!) and a sore throat, which I had before my bfp with DS. DH is convinced I'm pregnant too for reasons I'm a little embarrassed to say lets just say it's to do with dtd

As far aw I'm aware it's the hcg that causes the morning sickness. If it is indeed morning sickness would a hpt show a positive result given I'm feeling the effects already?

Has anyone had morning sickness this early on?? Or perhaps I'm just loosing my mind lol
