Period help!

K so I just had my first period since having my son at 8 weeks PP it was from July 2-6 which seemed awfully short to me because my periods are always a week or so long so i waited a couple days before not wearing a liner because I just knew I’d probably spot once more because that always happens to me. Well I never had any spotting afterwards. Weird. Maybe just my period trying to get back on track after not having one for a while? Idk. But tonight I went to use the bathroom and I had pinkish/brownish tinted discharge in my panties, there was nothing when I wipes. I feel like it’s been too long for it to be from my period and now I’m worried it could be implantation bleeding/spotting. 😩 I am not on birth control (yet! Waiting on my IUD to get in) but my husband and I have been using condoms religiously and have only had sex about 3 or 4 times since I was cleared by my dr at 6 weeks. I am now almost 10 weeks PP.

I guess what I wanna know is does it sound like I could be pregnant or is it just my body and period adjusting?? I’ll probably test just to ease my mind because we’ve been using protection every time but I know condoms aren’t 100%
