Early pregnancy symptoms HELPPPP🗣

Akashia

So I had my IUD skyla taken out September 19th. Well on October 2nd for three days straight I tested for ovulation and they were positive so I assume that week I was ovulating . So of course we had sex.. well according to my calendar I should of had my period the last 2 days but I haven’t. (I had a regular period while on BC) still no period. And the last two days I’ve been soooo sick including vomiting and smells of food. I tested last weekend and it was negative and had no sickness or anything.. but this weekend my body is dead tired and soooo nauseous.. should I test again tomorrow morning?? With my son I never experienced any sickness or symptoms of pregnancy AT ALL so this is all new to me and I know my body is off but idk what’s causing it 😬
