Two week wait

So our son is turning 3 on Saturday (cue the waterworks!!). Anyway, since about june we have stopped preventing getting pregnant again. I never went back on birth control after having my son bc we had a hard time conceiving and I blame bc for part of that. I now have hypothyroidism which my doctor feels may be related to my hormones getting thrown off from BC the first time. Anyway, we aren't necessarily trying to get pregnant but agreed what's meant to happen will. Well, last weekend we had sex twice during my ovulation cycle and I swear about 3 days ago I got the same type of cramping I did right before I got pregnant with our son. Then today I wiped when j peed and there was a very faint squiggle of blood, maybe implantation? My period is due on my son's birthday and it would be pretty cool if we found out we were going to be adding to our family. Trying not to get excited but I am deep down hoping. Plus I'm a teacher and this would put me due right at the end of June. Timing would be perfect. Fingers crossed!
