Maybe??

My stomach is bloated like crazy and my body is rejecting alchol. My breast constanly ache. My lower back hurts. I took one test and threw it away i went to take another test in the morning and it was negative. When i went to throw it away i saw the other one and it had a line. Waited till this morning it took another one and it was negative looked at the one from yesterday and it was still negative but that first one was positive what do I think? Maybe wait till few weeks or a week but I've been super tired just walking up the stairs I feel like I ran a mile I've been craving Diet Coke just like I did with my first pregnancy just very confused period.
