Hi, I have been having some dizzy spells over the last 3 days and have had a constant headache for 2 days now. I have been very tired during the day and my period was strange too, as i normally have a 5-6 day period which is quite heavy for the first 2 days then normal for the rest but this time it only lasted 3 days in total and was not heavy at all. I am 36 and I have never had these symptoms before, i am not sure if this is a possible pregnancy symptom as i have been trying for my 5th child for a few months now but since I had my period last week I counted it out, please help
