I've been trying to concieve but it's not happening.

My af suppose to had came on the 6th but I spotted light pink on the 7th it lasted for a day. Then on the 9th my af started it was mild bleeding red blood and slight cramping it lasted for 4 days. Afterwards like a day after my af went off I had intercourse then after that I had intercourse again. Now I'm feeling nauseated, gasy, dizzy, light headed, slightly cramping is this normal? Or is something wrong?
