Hi my n my husband are tying for a baby! My average cycle is 29 days since I have been monitoring about 4-5 mths now! This mth I started A day early and I think it may have been lighter than normal! I was sick the 5th day of my period which is the day I finish. The day after I felt really sick the last couple of days I feel a bit sick and been having lower and upper back pains! Two days a go we both started to take fertility supplement tabs, todAy I noticed that my stool is darker in colour. I've also noticed that I haven't been able to go to the toilet properly. Although bloaded this has been otherwise causing any pain. Could I be pregnant?
