Confused

Hi, 

I’ve been trying to get pregnant for around a year now. I recently found out my boyfriend has a low sperm count. We have been taking vitamins to help it etc.. We haven’t been to see a GP as of yet. Recently, I’ve been so thirsty and wanting to drink a lot of water and eat a lot of fruit. My nipples are sore and lumpy, that’s stopped now, still a bit sore but not as bad. I have took a pregnant test which are only cheap but when I put my wee on them it’s smudging.. I’m not due for another 2 days but I just feel different. Could anyone give me advise
