Are Early Pregnancy Symptoms different if it’s not the first child?

Br

I’ve been super in tune with everything about my body and mind. Looking for signs similar that I had with my first born, and mixing those in with what I read from posts and other blogs online. With my first, I don’t remember having implantation bleeding at all. However I do remember having stabbing pains in my uterus that felt like nerves fusing together so I took a test that day and it was positive, which was 2 weeks after intercourse. This time around, I have a little cramping here and there, and the past weekend there was faint (and I mean scarce)traces of pink in my CM. However CM has been pretty light and mostly sticky/dry for the past 6 days. Took a couple test and got a BFN so I decided I give up on testing and would just wait for AF (which is scheduled for Friday July 3). Well, this morning, I go pee and out of curiosity check my CM. It’s more creamy than it has been, there’s more of it, and a lot more pink/red mixed in it similar to photos I’ve seen of implantation bleeding.

Since I don’t really know what I’m looking for because I haven’t experienced this - I chose to check other symptoms. My breasts are not sore. My areolas are a little darker I suppose but I notice more my nipples are erect a lot of the time lately which isn’t typical. I’m having a headache every morning when I wake up. I started taking prenatals a week ago just in case. I guess after all this obsession with how I feel and what’s going on, if I end up indeed not being pregnant I’m going to feel really stupid for getting my hopes up and mistaking these signals as a sign. Also - my TWW isn’t up until Friday. I’m a mess. I broke down to my SO yesterday because I felt like he wasn’t really showing a whole lot of support when this was a joint decision. This will be his first child so I’m trying to be very mindful that maybe he’s just very scared and it makes it look like he’s not interested in talking about it. He held me for a while yesterday and everything is fine now and finally I can be open with him about what I’ve been up to these past 2 weeks (and the fact I’ve tested and didn’t tell him). Getting a negative after negative I was embarrassed and didn’t want to say anything to him so all the heartbreak and sadness and emotions have been bottled up this entire time up until last night. This week so far I’ve Been extremely sensitive and emotional but I always am during this time of my cycle.

I guess my point of my posts is to hopefully find out that I’m not alone with these things and there’s someone else out there TTC who can relate.
