could I be??

Amy
Ok I need some help my period was normal last month 10-15 my periods are 25-26 days apart and I'm pretty sure I felt myself ovulate as I usually do! My SO and I had sex the day after my period and for the next 4 straight days. We took a few days off and had sex again and again! Today my period is supposed to come on for the past couple of days I been feeling faint and dizzy I'm laying in bed and still feel weird! I ate dinner last night this morning felt nauseous! I have been pregnant 3 times before and always got dizzy not sure so early tho! Anyone else experience dizzy spells so early on??
