Possibly pregnant after birth control?

Okay, this may be sort of long. I was on the pil (low dose Minastrin) and missed 2 or 3 sometime 1/13 - 1/15. I went to my doctor and told her about it and that I just feel like my hormones are off and she changed me to Nuvaring. I put it in immediately 1/21 and proceeded with sex life as normal. I have not had a period in about 5 or 6 months on the pill and only had a little spotting on 1/18 and 1/19 about 6 days after taking out the ring. I took out my ring for good the other day .

I have had collostrum looking discharge from my breasts for almost 3 weeks, small red spots on my skin that do not itch or hurt for 2 weeks or more, occasionally my breasts/nipples tingle or hurt (but not achy). I've had a lowered immune system (viruses), increased sex drive. I don't feel nauseas like a I did with my first two pregnancies, or extremely fatigued. I am colder than normal. I actually feel slightly happier and more patient than normal lol. I am known to feel like I might be pregnant and test often so I keep telling myself that it's the same this time.

I have had negative pregnancy tests and a negative blood test as late as 2/25. I started ovulation tests since I'm not on bc anymore and not particularly trying to get pregnant.

Any thoughts for me? Possible pregnancy or truthfully negative?
