Am I silly to think I am pregnant?

Hi, my husband and I had unprotected sex thrice between July 22 and July 29. My periods was due 30July--1Aug. 2 days is the maximum my periods has been late for over 10 years for me (hence the range).

Today is Aug 12th. So around12 days late. I have thigh, leg and feet pain, I throw up once or twice a day, I feel cramp like pain in the vagina area, I felt dizzy a few times, I've started liking spicy food which my tongue is well-known to be intolerant of, my asthma has suddenly become severe and I have mild to severe back pain all through the day. It hurts me when my 14 month old nephew pushes my breast for support while trying to stand up.

I did home pregnancy test 4 times so far using products of 3 different companies. All gave negative result. I am frustrated why I am suffering all this if it isn't for a baby. Until I get confirmation, my husband isn't going to show any sympathy...in terms to letting me avoid carrying heavy weight, climbing stairs too often, travelling through difficult terrain for several hours, etc.

I don't want to take any strong medication for asthma, in case I am pregnant. I am avoiding caffeine too, which has been my cheer-drug and spirit for a long time. I do wish for the baby. I don't know if I can be a good enough mom, but I already love the possible baby. I surprised myself when my husband made me do physically demanding work by responding, "I am gonna kill you if I lose this baby!"

I don't know if there is a baby or if something is wrong with me. I talked to my mom. She says it's too early to know and cramps around vagina is not a good sign, it means the uterus is contracting...that I may be at risk of a miscarriage. My hCG level in blood went up when I was on migraine medication a year back. So I don't have faith in a blood test.

Is it possible to confirm a pregnancy this early through scanning? Is it wise to be cautious to avoid physical strain and check my diet or am I being ridiculous to be so careful when I don't even know if there's a baby?

My relationship with my husband is strained now because of how he's treating me emotionally and physically despite what I am going through. I don't want to lose my first baby for the sake of pampering my husband's ego. I love him, but I really don't want to risk a miscarriage for the sake of keeping him pleased.

My symptoms have not negatively affected our sex life. Adding this to let you know that I don't mean that I want abstinence for baby's safety. I only mean stuff like lifting 35-40 kilos.

I'll be happy to receive any advice or opinion, or just comment. Please don't be mean to me. It will be nice if someone can tell me if I could really be pregnant, is there any sense in me feeling hopeful? I like long replies...even if you don't know what to say.

Have you talked to your doctor or seniors person in your family?

Thanks for your reply. I think I had a miscarriage that time. Had a sudden pain when I was out, making me sit down on the ground. I had heavy bleeding for a day and it stopped. I saw doctors. They said it might have been late period. The person who did ultrasound said it's too early to know. I think I'll never know for sure whether I was pregnant.

However, now I am 5 months pregnant
