Curious

My fiance finished in me on july 14th. I took a plan b the next day (15th). He finished inside me again on the 18th. I didnt take another plan b. Because it sometimes tends to make me sick. Since the 23rd ive been havin bad headaches, mood swings and hot flashes. Also for the past couple of days ive found alot of the food that i eat on a normal basis to taste weird or just straight up disgusting.

I dont really think much of it im just curious to if any of you ladies have experienced any of this or something similar in the early stages of your pregnancies.?
