Help! I have been trying to conceive since August (no luck yet). We had sex on Sunday and I was supposed to start my period Monday. It's now Wednesday and no period.... Last month we had sex on my highest ovulation day.. Usually my periods are always on time. I just took a test and it was negative. Did I take the test to early? Did having sex so close to my period push my period back a couple days? Help! I'm starting to think something is wrong with me or him?!
