Try not to worry too much! I think most pregnancy symptoms come and go in the first trimester, I could feel so sick, absolutely exhausted and have aching boobs and cramping one day and then the next wake up and feel great! All my symptoms would be gone! Then 2 days later, they'd come back again and I'd regret wasting the 2 good days on worrying lol - Try not to stress about it but if you're really worried, pop in and let your GP know, can't hurt Good Luck!! xx
