i finished my pill on the 6th march and had a withdrawel period a few days later, on monday i started to take my folic acid tablets(400mg) and yesturday i was ill. keep getting hot flushes, feeling sick, fatigue, no appetite wot so ever. we did have unprotected sex once on monday but surely theres no chance that these are pregnacy symptoms. we didnt have sex purposely to try but just got carried away. has any1 else had any side effects off folic acid or does any1 know what these symptoms could be?
