So my and my DH have been trying to conceive since my ectopic pregnancy in March. My period was suppose to come on the June 20th, this morning I woke up with really bad cramps and sure enough it looked as if my period has started. Although it's really strange, it is really really light. I usual have heavy period, still feeling sick to my stomach and breast sensitivity. I am worried though because I did use a heating pad on high directly on my stomach this morning, does anyone now what effects that has on someone that is in early pregnancy? BTW I did take a pregnancy test on the 20th and it was negative
