Hi girls! I am one day late for my period and this morning I woke up with a cold sore! I have been experiencing nausea and light headness everyday. Also I had what might be (implantation bleeding) 6DPO, it was a light brown discharge stain on my panties (Sorry if TMI) and it lasted for one day. Today I am on 15 DPO and CD 36 and my cycle is 35 days long. Last month my cycle lasted for 29 days?? I haven't took a HPT because I am scared to get another BFN! Does women experience a little of nausea, light headness, dull headaches, backaches, bloating, fatigue, missed period and cold sores and still be pregnant? Does it sound like pregnancy?
