Please help...

Ok, so hopefully the shot is wearing off, I'm taking my one-a-day vitamins for her plus prenatal vitamins (gotta get me some folic acid in my system) since the last day for me to get my shot is when I restarted taking them I started spotting for like half a day, and it stopped (usually on the shot I "spot/bleed" for 3 weeks (unlike my periods for only 5 days... 😐) I've been feeling quite nauseous for about a week now. We've had sex for about a week straight now (6 days straight, took 1 day off, and then 1 more day) and I've noticed that when I was on the shot I wouldn't get that creamy feeling (ovulating) during the shot (understandable) but I started feeling that way around the time I was suppose to get the second one.. Now there are foods I loved to eat and now I can't eat them without gaggin ... 😭😭😭 (DO YOU KNOW WHAT ITS LIKE TRYING TO EAT ICE CREAM.... WITHOUT TRYING TO GAG!!!)

Anyways... I need to know what's going on 😭😭 please help... I've only gotten the first shot.. *first timer*
