So here it is, Me and my boyfriend are trying to concieve and well the first day of my last period was july/16, which means I was due to ovulate on the 30th-1st august right? And of course we done it around then, but im due to come on my period tommorrow (13 august), but, normally when im due I always come on two days early? Well ive had no period, so I thought maybe ill be on when im due? (they are never late) lately ive been having constant mild headaches (not bad) and mild cramps and twitches in my lower abdominals mainly to the left? Also, today ive really lost appetite and have eaten nothing but half a banana in the morning and a small bowl of pasta for dinner. Normally when im due for my period I eat loads and get bad backaches, severe stomach pains, bad headaches and I would just know when im coming on without checking the dates. But this time im not early and ive had the complete opposite symptoms to what I would normally have? Opinions please?
