Conception????

So my Flo app said my peak ovulation day was the 10th and this app said the 13th (today) I’ve had sex the 10,12,13 of this month just to insure we conceive! ( my husband and I have been trying to conceive for 7 months 🤞🏼) anywho after sex tonight I went to the bathroom and wiped and there was a good amount of very light pink blood. Then I waited a few more minutes and wiped again and it’s still there. I’m also having mild lower stomach cramps. Does this mean it’s implantation??? Or is it to early?
