Hi everyone, just need some advice on pregnancy tests I have taken this week. I first bought Crystal Clear Test which contained 2 tests and with the first one I didn't use morning urine. The next morning I tested with the second stick and in a 3 -5 min time mar it only showed up one line...I didn't think much of it so I threw it in the bin. 3 hours later I decided to check it or what reason I don't know and I saw a second line but it was faint blue. So then that afternoon I went to purchase First Response hpt and the first was negative as I used this in the afternoon, then did another one in the morning and that was negative and the third one did 3 hours later as I didn't go to the toilet since and had no fluids and that showed negative. I don't know what to make of this as I have been off birth control pill for 4 weeks and my nipples feel slightly sore, I have not had a period since off my birth control, I feel constipated and nauseous often. Any advice will be greatly appreciated. Thanks.
