Strange things arw happening to me.

So I had sex during my ovulation time. And for about a week I feel pain/pressure when ever I lay on my stomach. My taste buds are different. I like new foods, and foods I use to love I either hate or like less. My stress levels are through the roof lately. And im either getting fat or im super bloated. Havent missed the period yet. But is this normal stuff or... idk. Also I've been massively horney. And ask for a lot of attention lately.
