So my last af was alot lighter than normal...that was 2 weeks ago and since then iv been having rare bits of nausea...alot of uncomfortable painless cramps...slight backache. Iv done numourous tests and all have been bfn I went to the docs on thursday and he said its probably because iv started taking up swimming lately. Now i have constipation and im still very bloated. Im out tonight for my sisters bday celebrations and im wondering if i should be ok to drink as my last test yesterday was bfn again (surely if i was it wouldve shown up by now) Plus atm im currently at work and have just had to load up 11 boxes of marble into a customers car which didnt help my backache obviously. Should i go back to the docs when i have my next day off (although my next week day off is in two weeks)? Should i be ok to have a couple of drinks tonight?
