Myself and my boyfriend have been together for around 3 years now and have been trying to concieve for about 2 months now. A few weeks ago i was expieriencing symptoms ' tender breasts, bloatedness, bad headaches ' . But i have now come on my period early, my period is generally heavy and it has been but only for the first day and now it seems to be calming down alot. i have done one home pregancy test wich came back negative ... could i be pregnant or not ?
