Hi, in december I come on in the 14th then again son the 26th-30th. Past 2 weeks I've been feeling constantly sick, can here my pulse in my ears, tummy feels like pinching and feels funny it's like I knew I was pregnant but I've been doing tests like a crazy woman and most come up negative 2 came up with a very very faint positive. I tried a first response test today and negative :/ I don't know what to think !!! Advice plz ??? Xx
