Hey guys I need help

So I was just visiting with my husband overseas (he’s stationed out of the country) and while I was there towards the end of me visiting I spotted which is something very unusual for me to do. Especially seeing how I already had my period that month. It was about 4 or 5 days before I was supposed to start my period but there was very little of it. Anyway, I started my period on the third of October but it wasn’t like my normal one. I usually get a lot of blood clots (tmi sorry) but this time I only had a couple maybe a few which is very weird to me. Anyway, I’ve been exhausted this past week feeling a little dizzy and my appetite isn’t really there. I’m just worried because I’m supposed to be going to my obgyn in a couple days because they need to do some testing but I guess what I’m asking is should I take a pregnancy test within the next couple days or should I just wait to see the obgyn and ask her about it?? I’m just worried that if I am pregnant and she talks me out of testing if I’m pregnant (I tend to do what people tell me to) that I’ll lose the baby and I’m not sure if I’m ready to deal with that.. so what should I do? I need help
