TTC, did clomid, allergies acting up, any medicine recommendations?

Erika
I'm currently TTC, I did clomid 100mg CD 5-9, I'm currently on cycle day 11 and I have horrible allergies, stuffy nose & headache... does it matter what medicine I take. I don't want anything to affect me, I'm on round 2 of clomid. Praying for a positive ovulation this cycle
