No period for 3 years!

So I haven’t had a period in over 3 years because my daughters are only 18 months apart and i never got a period while breastfeeding. Anyways. This was our first month TTC and I took OPKs and it said I was ovulating. But then today I had some light pink/red blood when I wiped. Pretty sure it’s my period because I got a dark line on my opk almost 2 weeks ago. So I doubt it’s implantation. At least I know I’m ovulating and can hopefully try again next month! 😂🙌🏻
