Why is this happening!!!

Rebekah

Me and my husband have been trying to conceive the last couple of months. I have taken several pregnancy tests and they all are saying not pregnant. I even had the doctors do a pregnancy tests and it was negative, but it have been over 6 weeks since my last period. I am on some medications that I should not take during pregnancy, but my doctor won’t take me off till I am for sure. I am having morning sickness, tender breasts, always tired, I’m getting lightheaded randomly, and SUPER IRRITABLE! I bit my husbands head off last night cause he was kissing my neck, which I absolutely LOVE!!! Should I be considered or what should I do?
