37 day cycle...one pos test, one neg...WTf

[Miracleplz14]

Hey! So my fiancé and I are very confused...I am on day 37 of my cycle. My cycle has never ever been longer than 34 days my entire life! I had one very very faint positive and a negative. My nipples are sore and they have giant blue viens that just popped up a day ago and they are everywhere. My discharge is a white creamy, milky and I constantly feel wet(TMI). I have had a weird muscle ache sensation on and off for about a week now. I am bloated and look pregnant, my lower tummy is hard too (this is baby number 2 if I am.) I've had a headache or two. Eating very abnormal for my usual eating habits. But took a test this morning and it was neg! anyone have any experience?? My fiancé and I are keeping our fingers crossed

I took an equate test: light pos. at the 10 min mark
Took a first response: neg...
