If he's been around you through thick & thin then your pregnancy hormones shouldn't effect you'll relationship. If anything he should want to be around you more knowing that you're carrying his child...... .......I don't remember having cramps so far in my pregnancy but some people do so I'm guessing it's normal as long as you're not bleeding
Im pregnant and 18 as well, my little girl is due april 13(: congratulations on being pregnant, it is hard but its worth it. My fiance is 20, by the time shes born i will be 19 and he will be 21. Having a baby is going to bring on a lot of stress, you guys may fight more than usual because of your hormones. So between myhormones and my fiance's bipolar disorder, we do get in a lot of arguments. But everything calms down. Im kind of worried that once shes here we might fight more, and i definitely dont want that for her. Everyone says they dont think we will make it, but weve been proving them wrong. If you and your boyfriend really love each other im sure you will be fine, he will probably understand the hormone thing - even if he fights back. And yes that is normal, spotting and cramping is common in the first trimester, but if you bleed heavily or have clots thencall the doctor!
