Help?

So last month my period started the 14th. It was bad, heaviest bleeding and worst cramps I've ever had. I threw up a couple times had headache and got dizzy out of no where. It didn't end till the 28th. ( my normal periods last 4-5 days) when I went to the doctor on the 30th they said it could be a miscarage or just stress. They gave me prenadals and folic acid. I wasn't to worried after that. But I been thinking shouldn't I have this month's cycle by Now? Me and my spouse have been trying to have a baby for like 4 months now.
