Sick or symptoms ?

So I know pregnancy symptoms can mimic colds sometimes with the aches and tiredness and at this point Idk what to think. So I have SUPER irregular cycles. like no point in even tracking cause there's NO kind of pattern. I think average is 44 days ?But since I've given birth (7 months ago) I've had I think four cycles ranging from 30 days to 50 days 😭😭 So pretty much at this point I give up tracking. I know there have been colds and flus going around heavy this year so Idk what to think. let me get to the "symptoms" I've been pregnant before and this feels a lot like that but I keep getting negatives. So lately I've had headaches (I don't normally get them unless I'm prego) Normally my nips are completely numb. lately they're sensitive. I'm SO EXHAUSTED. Like making it hard to take care of my daughter exhausted. My hair won't take color (I've been dying my hair since I was 13 and I've never had this issue) and a whole bunch of other stuff but I'll save it for the sake of not making this post too long lol. anyways, what do yall think ??
