Me and my husband haven't been trying yet, but We had sex on the 20th and 23rd, and I've been having light cramps not bad, and been really gassy like I was with my first and my back has just started hurting, and yesterday was the day I start my period and I had very light pink spotting and it has stopped today. What do u think? should I wait a week and take a test. I really hope I am but I don't wanna get my hopes up.
