@Laci thank you so much for commenting back it certainly helps my anxiety!!! But I know this is TMI but we only got intimate the night I got my positive test and before it does that matter? X
Sperm can live in the vagina for 5 days so there's a chance you could be pregnant but in the future I'd recommend doing it after your positive test aswell! What worked for me was having sex every 2-3 days around ovulation so there was always alive sperm to raise my chances of getting pregnant x
ovulation can happen up to 2 days after a positive ovulation test so you may not actually be 13 dpo. Test again in 24-48 hours, good luck!!
