Hi, so about a week ago i had sex right after my period and we didnt use protection. Now i ve been feeling sick to my stomach (not throwing up), ive been getting bad headaches , stomach cramps here and there, i dont eat red meat and for the last 2 days i have been eating it non stop. Could my body be lacking something or could there be a bun in the oven that im not aware of? Oh, i should probably mention that I only have 1 ovary and fallopin tube on my left side so I know that makes getting pregnant slightly harder.
