Questions about first period !

So my first period just ended a few days ago, I spotted for a little less than a week off and on then my actual period lasted a full week.

Was anyone else’s period longer than normal?

Also another question or rather concern.. so the last day of my period was the 15th, so I’m assuming I’m in my fertile window rn, and today I had some creamy cm that was tinged pink.. is this normal with your first period pp? I had this with my daughter so I was a little taken aback but it’s not always a pregnancy sign, right?!

We had sex with a condom on the 16th and then again on the 18th. I’m not on bc due to personal reasons, and he’s suppose to be getting a vasectomy but has been procrastinating on making an apt..But basically we are not planning on having another baby anytime soon lol so we’ve just been sticking to condoms until he gets it done and I know that condoms are mostly effective but I can’t help but feel a little👌 nervous! I currently have 3 little ones as it is, my youngest 2 months and my oldest is 4..and this mama is exhausted😴

Yes of course I will test in a cpl weeks if I still feel concerned, I just want to get some opinions and see if anyone else has experienced anything like this with their first period postpartum
