Pregnancy Info HOME

Past 3 months my cycle has been very odd. In September my cycle came 5 days early on the 13 expected on the 18 never moves around that far in difference. Then in Oct came on the 11th so thought maybe I had switched to a 28 day cycle so this month, november, expected it on the 8th and nothing came. Today is the 12th so I'm 5 days late. Last week was very nauseas and experienced one day of vomitting and pounding headache. This week it's eased up but still get quizzy around certain smells. Also my br___ts just feel bigger like swollen and for awhile 2weeks almost 3 my nipples just felt sore like throbbing and super hurt if anything touched them. I've had a miscarriage before and on that one I had done a HPT which was negative only found out through blood tests. Hence why scared and unsure about taking a HPT because been suffering hugely emotionally from the loss of my last pregnancy. Sorry for such a long question but if anyone thinks I am pregnant or had these symptoms would like to know that I'm not going crazy lol. Also have had sharp pains on my stomach and back pain idk if that has anything to do with it either. Thanks!
