Chance of being Pregnant?

Ok so I have one daughter and when I was pregnant with her I bled off and on the whole time between cysts and I had a bleed in my uterus. So the last time we had sex was on ovulation in march. we arent currently even kissing each other because he is paranoid with getting me and my daughter sick when he is still working🤦🏼‍♀️ stressful time. Well anyways I obviously had my “period” end of March. But now I am two days late. TF :(. woke up this morning w the worst migraine of my L I F E. could it be stress could it be pregnancy? idk. yes i will get a test if i miss the whole thing but advice til then to keep my mind at ease is what i am currently looking for please and thank you
