Most symptoms of pregnancy don't really start until 6 weeks and for some women not until 8 weeks
Don't panic, i had no symptoms until about week 9, and even then, very minimal. Congrats on your pregnancy!
Its not necessary to have pregnancy symptoms... Every women is different love... I had bo symptoms what so ever till 7wks n thn thy hit me till 14wks... N nausea still didnt leave me till 20wks... So just relax n enjoy pregnancy... Plus if it was chemical pregnancy you would have started your normal cycles at normal times and blood test would hve showed less hcg levels... Miscarriage on the other hand is whole other story... But u dont hve to worry abt tht not unl3ss something is wrong or confirmed by u/s...
I've been reading up on a lot of early symptom accounts and I've noticed that for a lot of women they felt that they just had normal PMS but were in fact pregnant. Others didn't have any symptoms at all, or very few. So chances are you're fine!
