ATTENTION....I need advice I've been TTC for a few months now but I've had no luck well I'm well over a month late I've had acne breakouts which almost never happen. I've had frequent neasua light cramps now I have white spots on my nipples... I've taken two test about two weeks ago and they were negative. pregnancy is not the only thing I think about and we don't constantly have sex so it's not like I'm giving myself these symptoms and I already have one child I just just confused as to why I'm having these symptoms but not positive test
